Question

Expand the given expression using suitable identities.
(2x-3y)²​

Answer 1

$\huge\text\red{\underline{\underline{Answer}}}$

$\sf (2x-3y)²$

$\sf (a-b)²=a²-2ab+b²$

$\sf (2x)²-2(2x)(3y)+(3y)²$

$\sf 4x²-12xy+9y²$

$\sf\red{ (2x-3y)²=4x²-12xy+9y² }$

Answer 2

(2x−3y)²

(a − b)²=a² − 2ab + b²

(2x)²−2(2x)(3y)+(3y)²

4x²−12xy+9y²

(2x−3y)²=4x²−12xy+9y²
