No answers in integers, quadratic formula gives:
x = (3 +/- sqrt(9 + 200))/10
= (3 +/- 14.457)/10
= 17.457/10 or -11.457/10
= 1.746 or -1.146
5x2 + 3x - 1 does not have rational factors.
5x2 + 20x = 5x (x + 4)
5x2-46x+9 = (5x-1)(x-9)
5x2-18x+9 = (5x-3)(x-3)
With great difficulty!
x(5x - 4)
5x2
5x2 + x - 6 = (5x + 6)(x - 1) 5x2 - x - 6 = (5x - 6)(x + 1)
The GCF is 5x2
x(5x + 7)
5x(x+3)
5x2
