Question

Let f(x) = 2x2 − 2x + 7 and g(x) = x2 + 9x − 6. find f(x) − g(x). (1 point) x2 − 11x + 13 x2 − 11x + 1 x2 + 7x + 1 x2 + 7x + 13

Answer 1

`x^2-11x + 13`

Explanation:

Let
`f(x) = 2x^2 - 2x + 7` and
`g(x) = x^2 + 9x - 6`

We need to find f(x)- g(x)

Replace f(x) and g(x). then subtract the expressions

`f(x)-g(x) =(2x^2 - 2x + 7)- (x^2 + 9x - 6)`

Remove the parenthesis and multiply negative sign inside second parenthesis

`2x^2 - 2x + 7- x^2 - 9x + 6`

Combine like terms

`x^2-11x + 13`

Answer 2

f(x)-g(x)
=2x^2-2x+7-(x^2+9x-6)
=2x^2-2x+7-x^2-9x+6
=x^2-11x+13
