Question

expand (2x + 3y)²
what is the answer of this question? ​

Answer 1

Answer:

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

Step-by-step explanation:

it is in the form (a+b)^2=a^2+b^2+2ab

Answer 2

Step-by-step explanation:

$Given, (2x - 3y) ^{2} .$

$We \: know, \: that \:  (a + b) ^{2}  =  {a}^{2} + 2ab+ {b}^{2} .$

Then,

$(2x + 3y) ^{2}$

$\longrightarrow \: (2x) ^{2} + 2(2x)(3y)+(3y)^{2}$

$\longrightarrow \: 4x ^{2} + 12xy+9y^{2} \: Ans .$
