Question

G(x)=(-5x-1) (2x+8)Please help!​

Answer 1

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

Step-by-step 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

Answer:

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

Step-by-step 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:  $g(x) = -10x^2 - 42x - 8$
