Question

Is polynomial below a perfect square trinomial? If not, select the change that would make it a perfect square trinomi

25x² + 10x +4
A. The coefficient changes to a 16.
B. The x coefficient changes to a 20.
C. The constant value changes to a 16.
D. The polynomial is a perfect square trinomial.
Please select the best answer from the choices provided

Answer 1

(5x + 2)² = 25x² + 20x + 4, so

25x² + 10x + 4 is not a perfect square trinomial.

B. The x-coefficient needs to be 20.
