Question

6.f(x) = 2x + 3x +1g(x)=7X - 2x+7XFind h(x) = f(x) - gix)A.h(x) = -7% -5€ -5x-1B.h --- 5 -- |318

Answer 1

`\begin{gathered} f(x)=2x^2+3x+1 \\ g(x)=7x^2-2x+7x^3 \end{gathered}`
`\begin{gathered} h(x)=2x^2+3x+1-(7x^2-2x+7x^3) \\ =2x^2+3x+1-7x^2+2x-7x^3 \\ \end{gathered}`

rearrange the terms and simplify

`\begin{gathered} h(x)=-7x^3-7x^2+2x^2+3x+2x+1 \\ =-7x^3-5x^2+5x+1 \end{gathered}`

The right option is A
