Question

What is the expression in factored form?
9 x ^ 2 - 4

Answer 1

does it = 0?

Answer 2

If it does then it would be:

(3x - 2)(3x + 2)

Answer 3

Can you show work on how you do it please?

Answer 4

so you want no middle term which means you need two perfect squares which you have...

9 and 4

sqrt(9) = 3
sqrt(4) = 2

to cancel the middle term make one +2 and the other -2

Answer 7

(3x - 2)(3x + 2) final answer
