Question

A student factors 3x^2-12 to the following 3(x^2-4) which statement is true?
​

Answer 1

The expression is equivalent but is not completely factored

Explanation:

Given

3x² - 12 ← factor out 3 from each term

= 3(x² - 4) ← x² - 4 is a difference of squares

= 3(x - 2)(x + 2) ← completely factored
