Question

type the correct answer in each box. use numerals instead of words. simplify the following polynomial expression. $(-4x^{2}+17x + 9)-(-13x^{2}+5x + 16)$ $\underline{quad}x^{2}+\underline{quad}x + \underline{quad}$ reset submit

Explanation:

Step1: Distribute the negative sign

$(-4x^2 + 17x + 9) + 13x^2 - 5x - 16$

Step2: Combine $x^2$ terms

$-4x^2 + 13x^2 = 9x^2$

Step3: Combine $x$ terms

$17x - 5x = 12x$

Step4: Combine constant terms

$9 - 16 = -7$

Answer:

$9x^2 + 12x - 7$
The blanks are filled with 9, 12, and -7 respectively.
