Question

alegabric identities [2x+6y]2
$(2x + 6y) { ^{2} }$
​

Answer 1

Answer:

4x² + 6y² + 24xy

Step-by-step explanation:

$(2x+6y)^{2}$

{Using identity : (a + b)² = a² + b² + 2ab}

$(2x)^{2} +(6y)^{2} +2(2x)(6y)\\\\4x^{2} +6y^{2} +24xy$

Answer 2

Answer:

(2x+6y)^2

first step

algebraic Identity

(a+b)^2= a^2+b^2+2ab using this in the given question

now

step 2

(2x)^2+(6y)^2+2(2x)(6y)

4x^2+36y^2+24xy

this this the right answer
