I love factoring. The answer is (x+4)(9x+4)

9x2 + 40x + 16 =
9x2 + 36x + 4x + 16 =
9x(x+4) + 4(x+4) =
(9x+4)(x+4)
And yes, I LOVE factoring.

9x^2 + 40x + 16 = 9x^2 + 36x + 4x + 16 = 9x (x +4) + 4 (x + 4) = (9x + 4)(x + 4)

(9x + 4)(x + 4) it takes like 20 seconds to do using an algebra calculator.

9x² + 40x + 16
9x² + 36x + 4x + 16
9x(x + 4) + 4(x + 4)
(9x + 4)(x + 4)
