Answer:
36(x + 2)(x - 2)
Step-by-step explanation:
Step 1: Factor the expression
36x^2 - 144
36(x^2 - 4)
Answer: 36(x + 2)(x - 2)
36(x-2)(x+2)
36x^2 -144
Factor out 36 from each term
36(x^2 -4)
x^2 -4 is in the form of the difference of squares
(a^2 -b^2) = (a-b)(a+b)
x^2 -4 = (x-2) (x+2)
36(x^2-4) = 36(x-2)((x+2)
