Question

expand it
$(2x - 3y)^{2}$
​

Answer 1

Step-by-step explanation:

${(2x - 3y)}^{2} \\ \\ {(2x)}^{2} - 2 \times 2x \times 3y + {(3y)}^{2} \\ \\ {4x}^{2} - 12xy + {9y}^{2}$

Answer 2

Step-by-step explanation:

using ( a-b)^2=a^2 - 2ab + b^, we get,

(2x-3y)^2=(2x)^2 - 2(2x)(3y) + (3y)^2

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