Question

PLEASE HURRY Study these equations: f(x) = 2x – 8 g(x) = –5x What is h(x) = f(x)g(x)? h(x) = 10x2 – 40x h(x) = –10x2 + 40x h(x) = –10x + 40 h(x) = 10x – 40

Answer 1

h(x)=$-10x^{2}+40x$

Step-by-step explanation:

given ,$f(x)=2x-8$

given, $g(x)=-5x$

Given that $h(x)=f(x)g(x)$

Let $t_{1}$ be $k_{1}x^{n_{1}}$ where $k_{1} \text{ and } n_{1} \text{ are constants}$

Let $t_{2}$ be $k_{2}x^{n_{2}}$ where $k_{2} \text{ and } n_{2} \text{ are constants}$

We know that $t_{1}\times t_{2}=k1\times x^{n_{1}}\times k2\times x^{n_{2}}$=$k_1k_2x^{n_{1}+n_{2}}$

So,$h(x)=(2x-8)(-5x)$=$-10x^{2}+40x$
