To factor the expression 6x^2 - 216, you can first factor out the greatest common factor, which is 6. Then, factor the resulting quadratic expression.
-
Factor out the greatest common factor (GCF), which is 6: 6(x^2 - 36)
-
Recognize that x^2 - 36 is a difference of squares, which factors into (x + 6)(x - 6).
-
Substitute the factored form of x^2 - 36 into the expression: 6(x + 6)(x - 6)
So, the factored form of 6x^2 - 216 is 6(x + 6)(x - 6).
