Factor completely 4x^2 − 32
Blababa [14]

Answer: 4(x+2\sqrt{2})(x-2\sqrt{2})

Step-by-step explanation:

We can first take out the common factor of 4, as both 4x² and -32 are divisible by 4.

4(x^2-8)

From here, we can assume that x²-8 is a difference of two squares even though 8 is not a perfect square.

<em>For review, a difference of two squares </em>a^2-b^2 can be factored into (a+b)(a-b).

4(x^2-8)\\4(x+\sqrt{8})(x-\sqrt{8})\\4(x+2\sqrt{2})(x-2\sqrt{2})
