The factors are [3x + 5 - 2*sqrt(10)] and [3x 5 + 2*sqrt(10)].
10x^2 - x - 2 = (5x + 2)(2x - 1)
That would depend on the plus or minus value of 2 which has not been given.
2x+8x-2=22 10x-2=22 10x+2=+2 10x=24 10/10=24/10 x=2.4
8x^2 + 6x - 5 = 8x^2 + 10x - 4x - 5 = 2x * (4x + 5) - (4x + 5) = (2x -1) * (4x + 5)
