Answer:
Option D is correct, i.e. (4xy - 3z)² = 16x²y² -24xyz + 9z², a perfect square trinomial.
Step-by-step explanation:
Given the expression is (4xy - 3z)².
Using the formula, (a - b)² = a² -2ab +b².
(4xy - 3z)² = (4xy)² -2(4xy)*(3z) + (3z)²
(4xy - 3z)² = 16x²y² -24xyz + 9z²
It is a trinomial expression and we got it from squared binomial.
Hence, option D is correct, i.e. (4xy - 3z)² = 16x²y² -24xyz + 9z², a perfect square trinomial.
