Question

Which is equivalent to (4 x y minus 3 z) squared, and what type of special product is it?

Answer 1

Answer:

$16x^{2}y^{2}-24xyz+9z^2$

It is a perfect square trinomial.

Step-by-step explanation:

The square of a binomial can be solved like this:

$(a+b)^2=a^2+2ab+b^2$

We have the expression:

$(4xy-3z)^2$

Then, we consider a and b as:

$a=4xy\\ b=-3z$

The solution would be:

$a^2=(4xy)^2=4^2x^2y^2=16x^2y^2$

$b^2=(-3z)^2=(-3)^2z^2=9z^2$

$2ab=2(4xy)(-3z)=-24xyz$

$(4xy-3z)^2=16x^2y^2-24xyz+9z^2$
