Question

Select the polynomial that is a perfect square trinomial.

36x2 - 4x + 16
16x2 - 8x + 36
25x2 + 9x + 4
4x2 + 20x + 25

Answer 1

option c

Explanation:

Answer 2

none of the above

Explanation:

• 36x²-4x+16 = (6x)²- 2*2*x+ 4² this isn't a perfect square trinomial
• 16x²-8x+36 = (4x)² - 2*4*x+6² this isn't a perfect square trinomial
• 25x²+9x+4= (5x)²+2* 9/2 *x+ 2² this isn't a perfect trinomial
• 4x²+20x+25 = (2x)² + 5*4*x+5² this isn't a perfect trinomial square
