Question

Factor completely: 36x2 − 49

(6x − 1)(6x − 49)

(6x + 1)(6x − 49)

(6x + 7)(6x − 7)

(6x − 7)(6x − 7)

Answer 1

\(a^2-b^2=(a+b)(a-b) \) in your case \(a=6x,b=7\)

Answer 2

I kept getting that it cannot be factored...

Answer 3

So it would be (6x + 7)(6x − 7)?

Answer 4

yes

Answer 5

(6x)^2 - 7^2 think of it like that as @satellite73 said

Answer 6

your job was to recognize that \(36x^2=(6x)^2\) and that \(49=7^2\)
