# examples of simplifying polynomials

Question:Create a unique example of dividing a polynomial by a monomial and provide the simplified form. (PLEASE) Explain, in complete sentences, the two ways used to simplify this expression and how you would check your quotient for accuracy.

Answers:(x - 2x + x 1) : ( x- 2)= the quotient 3x +4x+ 9 and reminder 17 Here is the method for calculation 3x +4x+ 9 ------------------------ ** x-2 / 3x - 2x + x 1 \ first 3x divide by x the result is 3x **** 3x - 6x *********** 3x multiply by ( x-2) ------------------- * - ******substraction *******4x + x **********divide again by x etc +4x *******4x -8x ********** 4x multiply by x-2 --------------------* -*******substraction ....etc *********+9x - 1 *********+9x -18 -----------------------* - ************+17 ***** here is the rest because 17 can t be divided by x you can do the same way for x +x-2 / 2x -0x + 3x - 2x + x 1 \

Question:this is the question: Explain how to multiply a monomial by a polynomial. Also include examples where you need to simplify after multiplying . HELP! PLEASE AND THANK YOU .

Answers:1. Multiply term by term. 2. Add/subtract all numbers with same variables. Example: (x+1)(x +x+1) x +x +x+x +x+1 x +2x +2x+1

(8x2 + 5) (3x2 x + 7)

Answers:Since the questions are in multiple choice, I'll only provide the answers. 1: 4th degree polynomial 2: 10x3 + 14x2 4x4 + x 3: x7y5 4: 10x + 1 5: 7x3 + 4x2 4x 6: 10a2 + 9a 10 7: 1 over x to the 5th power 8: 49x6y6 9: x18 10: 4 11: x4 12: A polynomial in standard form is to arrange the monomials in decreasing powers. For instance, if we have 3x + x3 + 2 - 4x2, the standard form is x3 - 4x2 + 3x + 2. 13: To simplify the expression (8x2 + 5) (3x2 x + 7): First, we look at the first term of the first polynomial and find if there are like terms with the other polynomial. In this case, we have 8x2 and 3x2, when subtracted would give us 5x2. Second, we look at the next power of x. Only the second polynomial has an x with power 1. Thus, we have x (since negative of negative x provides a positive x). Third, we subtract the numerical constants for both polynomials, 5 - 7, yielding -2. Finally, we combine the results for each step: 5x2 + x - 2
