Question

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

What is the completely factored form?

Answer 1

Its A

Explanation:

I think its the first set so I'll expand it:-

(x + 3)(x - (-1 + √3)(x - (-1 - √3))

= (x + 3)( x + 1 - √3)(x + 1 + √3)

= (x + 3)(x^2 + x + √3 + x + 1 + √3 -√3x - √3 - 3)

= (x + 3)( x^2 + 2x - 2)

= x^3 + 2x^2 - 2x + 3x^2 + 6x - 6

= x^3 + 5x^2 + 4x - 6
