Question

simplify :(2a+3)²-(2a -3)²​

Answer 1

Answer:

(24a+36)

Step-by-step explanation:

(2a+3)²-(2a-3)²

= Using (a)²-(b)²= (a-b)(a+b)

= (2a+3-2a+3)(2a+3+2a+3)

= ( 6)(4a+6)

= (24a+36)

Have a nice day !

Answer 2

As we know , $\red{ {a}^{2} - {b}^{2} = (a + b)(a -b )}$

$\sf \implies(2a + 3) ^{2} - (2a - 3) ^{2} \\ \sf \implies \: (\cancel{2a}+3\cancel{-2a}+3)(2a+3+2a+3)\\\sf \implies (6) (4a+6)\\ \therefore \sf 24a + 36$
