Question

Which is equivalent to (4xy – 3z)2, and what type of special product is it?

Answer 1

Hello,

Answer D
16x²y²-24xyz+9z² a perfect square trinomial  which
le square of the difference of 3z from 4xy.

Answer 2

Answer:

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

Step-by-step explanation:

$(4xy - 3z)^2$

Given expression has exponent 2, so we multiply it twice

$(4xy - 3z)(4xy-3z)$

Apply FOIL method to multiply the parenthesis

multiply 4xy inside the second parenthesis

and multiply -3z inside the second parenthesis

$4xy(4xy-3z)=16x^2y^2-12xyz$

$-3z(4xy-3z)=-12xyz+9z^2$

$16x^2y^2-12xyz-12xyz+9z^2$

Combine like terms

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