Question

(3y+2)^2 solve using identity​

Answer 1

Step-by-step explanation:

(3y+2)^2

by using

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

(3y+2)^2= 9y+12+4

Answer 2

Answer:

= 4x²+ 9y²+ 12xy

Step-by-step explanation:

(a+b)²= a²+ b² + 2ab

putting a=2x and b=3y

= (2x)² + (3y)² + 2(2x)(3y)

= 2²× x²× 3² × y² + (2 × 2× 3 ) (x × y)

= 4x²+ 9y²+ 12xy
