The exterior of the Lincoln Memorial in Washington, D. As we can confirm from the dimensions above, the height is 30 m. We can use similar methods to find any of the missing dimensions. We can also use the same method if any or all of the measurements contain variable expressions.
To find the height of the solid, we can use polynomial division, which is the focus of this section. We are familiar with the long division algorithm for ordinary arithmetic.
We begin by dividing into the digits of the dividend that have the greatest place value. We divide, multiply, subtract, include the digit in the next place value position, and repeat. Another way to look at the solution is as a sum of parts. This should look familiar, since it is the same method used to check division in elementary arithmetic. We call this the Division Algorithm and will discuss it more formally after looking at an example.
Division of polynomials that contain more than one term has similarities to long division of whole numbers. We can write a polynomial dividend as the product of the divisor and the quotient added to the remainder. The terms of the polynomial division correspond to the digits and place values of the whole number division. This method allows us to divide two polynomials. We can identify the dividend, the divisorthe quotientand the remainder.
Given a polynomial and a binomial, use long division to divide the polynomial by the binomial. This division problem had a remainder of 0. This tells us that the dividend is divided evenly by the divisor, and that the divisor is a factor of the dividend. Synthetic division is a shorthand method of dividing polynomials for the special case of dividing by a linear factor whose leading coefficient is 1.
Polynomial Long Division
There is a lot of repetition in the table. Synthetic division carries this simplification even a few more steps. Collapse the table by moving each of the rows up to fill any vacant spots.
The process starts by bringing down the leading coefficient. The bottom row represents the coefficients of the quotient; the last entry of the bottom row is the remainder.When multiplying, remember the Product Rule of Exponents :.
Step 1: Multiply the first term of the first polynomial across the terms of the second polynomialand then add those products:.
Step 2: Multiply the second term of the first polynomial across the terms of the second polynomialand again add the products:. Step 3: Add the products from Step 1 and Step 2 by combining like terms.
Remember that variables with different exponents are not like terms. Next, multiply each term to simplify and combine like terms. Note: Be careful with negative signs. To solve, you can use the commutative and associative properties of multiplication to group like-terms together. Therefore, the correct answer is.

Special Education.In this lesson, I will go over five 5 examples with detailed step-by-step solutions on how to divide polynomials using the long division method. You would solve it just like below, right? If you can do the simple numerical division by the long method, as shown above, I am convinced that you can do the problems below. The only added thing is the division of variables. Example 1 : Divide using the long division method.Polynomials - Long Division
Solution: I need to make sure that both the dividend stuff being divided and the divisor are in the standard form. A polynomial in standard form guarantees that their exponents are in decreasing order from left to right. By quick examination, I hope you agree that both our dividend and divisor are indeed in standard form.
That means we are now ready to perform the procedure. Make sure to align them by similar terms. Notice that the first column from the left cancels each other out.
Seeing a pattern now? It means the divisor is a factor of the dividend.
Example 2 : Divide using the long division method. This time around you are dividing a polynomial with four terms by a binomial. Remember that example 1 is a division of polynomial with three terms trinomial by a binomial. Hopefully, you see a slight difference. Again the first column cancels each other out. Looks like a pattern to me! Bring the product below. Divide the leading term of the bottom polynomial by the leading term of the divisor. Example 3 : Divide using the long division method.
This is a critical part to correctly apply the procedures in long division. STEP 5 : Put the result under the dividend. Put the answer above the division symbol. STEP 13 : Go down by distributing the answer in partial quotient into the divisor, followed by subtraction. The remainder is equal to Example 4 : Divide the given polynomial using long division method. Solution : The dividend is obviously missing a lot of variable x.
I need to rewrite the problem this way to include all exponents of x in descending order:. Example 5 : Divide the given polynomial using the long division method. Both the dividend and divisor are in standard form, and all powers of the variable x are present. This is wonderful because we can now start solving it. The solution to this problem is presented in the animated picture.
