Question

3) Using identity, find: (2x + 3y)²
​

Answer 1

Answer:

${4x}^{2} + 12xy + {9y}^{2}$

in this the identity use is (a+b)^2

Answer 2

Answer:

4x^2+12xy+9y^2

Hope This Answer Helps You!

Step-by-step explanation:

Identity:- (a+b)^2= a^2+2ab+b^2

=2x^2+2*2x*3y+3y^2

=(2x^2)+12xy+(3y^2)

=4x^2+12xy+9y^2
