Question

Using the rules for special cases, what is the result of?

Answer 1

The correct answer is Option C 4x² -8x + 4

Explanation:

(a + b)² = a² + 2ab + b²

To find (-2x + 2)²

Here a = -2x and b = 2

(-2x - 2)² = (-2x)² + 2*(-2x)*2 + 2²

(-2x - 2)² = 4x² -8x + 4

Therefore the correct answer is option C . 4x² -8x + 4

Answer 2

C) 4x^2 -8x +4[/tex]

Explanation:

(-2x+2)^2

we apply (a+b)^2 formula

`(a+b)^2 = a^2 + 2ab +b^2`

a= -2x and b= 2

Replace 'a' with -2x and 'b' with 2

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

(-2x)^2 is 4x^2

`(-2x+2)^2 = 4x^2 -8x +4`

option C is the answer
