Step-by-step explanation:

Given : Expression (1.5x-4y)(1.5x+4y+3)-4.5x+12y(1.5x−4y)(1.5x+4y+3)−4.5x+12y

To find : Simplify the expression ?

Solution :

Simplify the expression by solving the bracket,

(1.5x-4y)(1.5x+4y+3)-4.5x+12y(1.5x−4y)(1.5x+4y+3)−4.5x+12y

=2.25x^2+6xy+4.5x-6xy-16y^2-12y-4.5x+12y=2.25x

2

+6xy+4.5x−6xy−16y

2

−12y−4.5x+12y

Take like terms together,

=2.25x^2-16y^2+6xy-6xy-4.5x+4.5x+12y-12y=2.25x

2

−16y

2

+6xy−6xy−4.5x+4.5x+12y−12y

=2.25x^2-16y^2=2.25x

2

−16y
