Question

Which expression is equivalent to 2x^2 – 2x + 7?

Answer 1

Answer:

option A is correct

Step-by-step explanation:

We simplify the given options

(a) (x^2-5x+13)+(x^2+3x-6)

combine like terms

$x^2-5x+13+x^2+3x-6$

$2x^2-2x+7$

(b)(4X^2-6X+11)+(2X^2-4X+4)

combine like terms

$4x^2-6x+11+2x^2-4x+4$

$6x^2-10x+14$

(c) (5X^2-8X+120)+(-3X^2+10X-13)

combine like terms

$5x^2-8x+120-3x^2+10x-13$

$2x^2+2x+107$

Answer 2

that equation equals (2x + 7)(x - 2)
