Question

factorise
a2-(2a+3b)2​

Answer 1

Answer:

Step-by-step explanation:

a² - (2a + 3b)² = (a+2a+3b) (a- 2a+3b)

                       =  ( 3a + 3b ) ( a + 3b)

                       =   3( a + b) ( a + 3b)

                       

Answer 2

Your answer is :-

${a}^{2} - {(2a + 3b)}^{2} \\ \\ = (a + 2a + 3b)(a - 2a - 3b) \\ \\ = (3a + 3b)( - a - 3b)$
