Question

can anyone factor 16xsquared -25

Answer 1

(4x-5)(4x+5)

Answer 2

Okay how did you do it?

Answer 3

Difference between two squares. (a-b)(a+b)=a^2-b^2

Answer 4

It's a difference of squares function.
IF you can sq.root both sides you do so and then put them into the form of (_x - _) (_x +_)
since there is a + and a - in the binomials the middle number is cancelled out.

Answer 5

ah. i see.
