Question

G(x)=(-5x-1) (2x+8)
Please help!​

Answer 1

Answer: g(x)= -10x2-42x-8

Explanation:

G(x)=(-5x-1)(2x+8)

Open the bracket

G(x)=(-10x2-40x-2x-8)

G(x)=(-10x2-42x-8)

G(x)= -(10x2+42x+8)

Answer 2

`g(x) = -10x^2 - 42x - 8`

Explanation:

Step 1: FOIL out

`g(x) = (-5x - 1)(2x + 8)`

`g(x) = (-5x * 2x) + (-5x * 8) + (-1 * 2x) + (-1 * 8)`

`g(x) = -10x^2 - 40x - 2x - 8`

`g(x) = -10x^2 - 42x - 8`

Answer:
`g(x) = -10x^2 - 42x - 8`
