Question

(5b+2)(5b-2)срочноо помогите

Answer 1

25b^2-10b+10b-4=25b^2-4

Answer 2

To multiply these two expressions, we can use the FOIL method, which stands for First, Outer, Inner, Last.

(5b+2)(5b-2) = (5b)(5b) + (5b)(-2) + (2)(5b) + (2)(-2)

Simplifying:

= 25b^2 - 10b + 10b - 4

= 25b^2 - 4

Therefore, (5b+2)(5b-2) = 25b^2 - 4.
