Question

expand (2x+3y)^2 using (a+b)2^​

Answer 1

Answer:

Hey dear here is your answer

according to given question

⇒$(2x+3y)^2$  is in the form of $(a+b)^2$

So the formula of $(a+b)^2$

⇒$(a+b)^2 = a^2+2(a)(b)+b^2$

Apply this to the equation that is $(2x+3y)^2$

⇒$(2x+3y)^2=(2x)^2+2(2x)(3y)+(3y)^2$

and now we will get the answer

⇒$2x*2x+2(2x)(3y)+3y*3y$

⇒$4x^2+2*2*3*xy+9y^2$

⇒$4x^2+12xy+9y^2$

So your final answer is $4x^2+12xy+9y^2$
