16x2 + 40x + 25 = 16x2 + 20x + 20x + 25 = 4x(4x + 5) + 5(4x + 5) = (4x + 5)(4x + 5) = (4x + 5)2
32
yes
sqrt(10x)*sqrt(8x) = sqrt(80x2) = sqrt(16x2*5) = sqrt(16x2)*sqrt(5) = 4x*sqrt(5)
8x4=32 16x2=32 32x1=32
The GCF is 2.
I believe the GCF (Greatest Common Factor) would be 8x I believe the GCF (Greatest Common Factor) would be 8x
The GCF is 8x.
2x(8x-7)
16x2 - 25 = (4x + 5) ( 4x - 5)
16x2 - 25 = (4x + 5) (4x - 5)
34-132
(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)
4x times 4x equals 16x2.
