F(x)=(x-4)(x+2) i need help
Westkost [7]

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

cosΘ = - 0.925

Since cosΘ < 0 then Θ is in the second or third quadrant.

Since 0° ≤ Θ ≤ 180° then Θ is in the second quadrant. thus

Θ = cos^{-1}(- 0.925) = 157.7° ← angle in second quadrant
