2y2 + 9y - 2 this will not factor using integers what is what most algebra teachers will tell you is 'prime'but ... make an equation ... 2y2 + 9y - 2 = 0use the quadratic formula to solvey = [-9 (+/-) sq rt (81 -4x2(-2))] / (2x2)y = [-9 (+/-) sq rt (97)] / (4) now separate thesey = [-9 + sq rt (97)] / (4)y = [-9 - sq rt (97)] / (4) rewrite as equal to zero(y - [-9 + sq rt (97)] / (4)) =0(y - [-9 - sq rt (97)] / (4)) = 0 apply zero product property in reverse(y - [-9 + sq rt (97)] / (4))(y - [-9 - sq rt (97)] / (4)) = 0these, as weird as they may look, are the factors.
