Simplify (2p+3)2 - (2p-3)2 (give proper detailed answer with all steps, the 2 is the symbol of square)

24p

Step-by-step explanation:

This is the difference of 2 squares:-  a^2 - b^2 = (a + b)(a - b).

So here we have:-

(2p + 3)^2 - (2p - 3)^2

= (2p + 3 + (2p - 3))(2p + 3 - (2p - 3))

= (2p + 3 + 2p - 3)(2p + 3 - 2p + 3

= 4p * 6

= 24p   (answer)
