Question

X²-4 this is the difference of square help please

Answer 1

Answer:

(x - 2)(x + 2)

Step-by-step explanation:

If this is a difference of squares, it factors like this.

(x - 2)(x + 2)

The general rule is x^2 - a^2 factors into sqrt(x^2) +/- sqrt(a^2)

That always produces 2 factors: (x + a)(x - a)
