Which shows a perfect square trinomial? a.50y^2-4x^2 b.100-36x^2y^2 c.16x^2+24xy+9y^2 d.49x^2-70xy+10y^2

Choice C is correct:  16x^2 + 24xy + 9y^2

Step-by-step explanation:

The easiest way to tell these is that if the parenthesis are exactly the same it will be a perfect square trinomial.

(4x + 3y) (4x + 3y)

16x^2 + 12xy + 12xy + 9y^2

16x^2 + 24xy + 9y^2

The answer is c
