Question

Factorize: (2x + 3y)² + 2(2x + 3y) (x + y) + (x + y)² *​

Answer 1

Step-by-step explanation:

let 2x+3y =a

x+y =b

.so (2x + 3y)² + 2(2x + 3y) (x + y) + (x + y)² *is in the form a^2+b^2+2ab

now a^2+b^2+2ab =(a+b) ^2

putting value of a and b

(2x+3y+x+y)^2

=(3x+4y)^2

=9x^2+16y^2+24xy
