Answer 1

Hope this helps you.

Answer 2

Answer:

$(2a-3b)^2=4a^2+9b^2-12ab$

Step-by-step explanation:

Given :

We are given the expression

(2a - 3b)

To Find:

Square of the given expression

Solution :

we are given the expression  ( 2a - 3b )

we have to find the value of  $( 2a -3b )^2$

since we know that $(x-y)^2=x^2+y^2-2xy$

$(2a-3b)^2=(2a)^2+(3b)^2-2(2a)(3b)$

                $=4a^2+9b^2-12ab$

Hence by using the identity

$(x-y)^2=x^2+y^2-2xy$

we get

$(2a-3b)^2=4a^2+9b^2-12ab$
