16x2 - 25 = (4x + 5) (4x - 5)
34-132
4x times 4x equals 16x2.
factor the trinomial 16x^2+24x+9
There is a formula for the "difference of squares." In this case, the answer is (4x + 3)(4x - 3)
16x2 - 25 = (4x + 5) (4x - 5)
16x2 + 40x + 25 = 16x2 + 20x + 20x + 25 = 4x(4x + 5) + 5(4x + 5) = (4x + 5)(4x + 5) = (4x + 5)2
(4x + 5)(4x + 5)
4x+516x2 + 40x + 25= (4x + 5) (4x + 5)
The GCF is 2.

(4x-3)(4x+3)
(4x + 6)(4x - 6)
If that's 16x2 + 72x + 81, that factors to (4x + 9)(4x + 9) or (4x + 9)2
(4x+1)(4x-3)
The GCF is 8x.
4x times 4x equals 16x2.
