Question

F(x)=(x-4)(x+2) i need help

Answer 1

Answer:

$x^2 - 2x - 8$

Step by step explanation:

Distribute the x as well as the -4  

x * x = x^2

x * 2 = 2x

-4 * x = -4x

-4 * 2 = -8

Combine all the like terms, which means terms with the same variable or regular integers must be either added or subtracted amongst each other.

2x + -4x = -2x

The final answer after combining all the like terms is

x^2 - 2x - 8
