(2a+3b)(2a-3b)
By the identity (a+b) (a-b) =(a^2-b^2)
We have,
(2a)^2-(3b)^2
=4a^2-9b^2
By the identity (a+b) (a-b) =(a^2-b^2)
We have,
(2a)^2-(3b)^2
=4a^2-9b^2
mysticd:
a,b are variables in the problem , so plz change the identity with different variables like x,y
yeah true.

It shows the formula:
(a+b)(a-b)=a²-b²
here,a=2a
b=3b
(2a+3b)(2a-3b)=(2a)²-(3b)²
=4a²-9b²
hope it helps................
