Factorise it
9b^2+24ab+12a^2
Answer :: 3(b+2a) (3b+2a)

I need steps

Answer 1

Step-by-step explanation:

9b^2 + 24ab + 12a^2

multipying 9 and 12 we get 108

now, 108= 18x6

therefore, 9b^2 + 6ab + 18ab + 12a^2

= 3b( 3b+2a ) + 6a( 3b+2a )

= (3b +6a) (3b+2a)

now, taking 3 common we get

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