Expand the following by using suitable identity (6x-7) (6x+7)..

Helo plzz !..

36x^2-49

Step-by-step explanation:

You could remember that (a-b)(a+b) is just a^2-b^2, so you could directly plug in 6x for a, and 7 for b, and get the

36x^2-49

(optional) to show that (a-b)(a+b) is really a^2-b^2, we can distribute using foil:

a^2+ab-ba-b^2

The ab's cancel out, leaving you with: a^2-b^2.

the correct answer is x/3+10≥32

hope this !
