If that's 16x2 + 72x + 81, that factors to (4x + 9)(4x + 9) or (4x + 9)2
Yes, and this is how. 16 x 2 - 9 16x2=32, 32 - 9 =23, so 23 is your answer! Good Question!
34-132
(4x-3)(4x+3)
factor the trinomial 16x^2+24x+9
2(4x + 9)(2x + 5)
4x3 + 16x2 - 180x = 4x(x2 + 4x - 45) = 4x(x + 9)(x - 5)
(4x + 3)(4x + 3) (4x + 3)2
16x2 - 25 = (4x + 5) ( 4x - 5)
16x2 - 25 = (4x + 5) (4x - 5)
The GCF is 2.
(4x + 6)(4x - 6)
