Answer 2

$(1.5x-4y)(1.5x+4y+3)-4.5x+12y=2.25x^2-16y^2$

Step-by-step explanation:

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

To find : Simplify the expression ?

Solution :

Simplify the expression by solving the bracket,

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

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

Take like terms together,

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

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

Therefore, $(1.5x-4y)(1.5x+4y+3)-4.5x+12y=2.25x^2-16y^2$
