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


16x2y2 + 9z2, the difference of squares

16x2y2 + 9z2, a perfect square trinomial

16x2y2 – 24xyz + 9z2, the difference of squares

16x2y2 – 24xyz + 9z2, a perfect square trinomial

Verified Answer :

the last choice is right sure because this is a perfect square trinomial

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

hope this will help you

Answer:

Option D is correct

\(16x^2y^2-24xyz+9z^2\)

a perfect square trinomial

Step-by-step explanation:

Using a perfect square trinomial:

\((a-b)^2 = a^2-2ab+b^2\)          ....[1]

Given the expression:

\((4xy-3z)^2\)

let a = 4xy and b = 3z

then;

Substitute in [1] we have

\((4xy-3z)^2 = (4xy)^2-2(4xy)(3z)+(3z)^2\)

Simplify:

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

Therefore, the expression which is equivalent to \((4xy-3z)^2\) is \(16x^2y^2-24xyz+9z^2\) and type of special product is:  perfect square trinomial
