Question

Expand (2x-3y)2
$(2x - {3y)}^{2}$
​

Answer 1

Answer:

Using Formula (a−b)2 = a2−2ab+b2

So, (2x−3y)2 = (2x)2−2(2x)(3y)+(3y)2

(2x−3y)2=  4x2−12xy+9y2

⇒ Solution (2x−3y)2 = 4x2+9y2−12xy

Answer 2

Explanation:

(2x-3y) (2x-3y)

(X²-2XY+Y²)

X=2x

Y=3y

2x²-(2*2x*3y)+3y²

4x²-12xy+9y² is your answer

I hope u r understood
