Question

simplify (2/3x-3/2y)square =(2/3x)square - ______ +(3/2y)square

Answer 1

Answer:

2*(2/3x)*(3/2y)

Step-by-step explanation:

using  the formula

(a-b)^2= a^2 - (2*a*b) + b^2

we have

a=2/3x

b= 3/2y

hence the other term is

2*(2/3x)*(3/2y)

=2xy

Answer 2

Answer:

Step-by-step explanation:

LHS:

(2/3x-3/2y)^2=4x^2/3+9y^2/4-2(2/3x)(3/2y)=4x^2/9+9y^2/4-2xy

RHS:

(2x/3)^2-a+(3y/2)^2

=4x^2/9-a+9y^2/4

LHS=RHS

4x^2/9+9y^2/4-2xy=4x^2/9-a+9y^2/4

a=2xy
