12x2-23x+10 = (3x-2)(4x-5) when factored
(4x - 7)(3x + 5)
5*2-3x-1 = 0 10-3x-1 = 0 -3x = 1-10 -3x = -9 x = 3
factors are (4x + 1)(3x - 2) so y = 0 when x = minus a quarter and x = two-thirds
(4x - 1) (3x + 2)

12x2 - 7x + 1 = 12x2 - 4x - 3x + 1 = 4x(3x - 1) - 1(3x - 1) = (3x - 1)(4x - 1)
9x2 - 6xy + y2 - 81 = (3x - y)2 - 81 = (3x - y - 9)*(3x - y + 9)
12x2-x-35 = (4x-7)(3x+5)
12x2 + 7x + 1 = 12x2 + 3x + 4x + 1 = 3x*(4x + 1) + 1*(4x + 1) = (4x + 1)*(3x + 1)
