Factor to this equation out, the easiest way is to solve for the two x values that add up to -1 but when multiplied is equal to -6. It should look like this: (x +- ?)(x +- ?). The factored out form is then (x - 3)(x +2), because -3 + 2 = -1 and when multiplied together gives -6. x - 3 = 0 x = 3 x + 2 = 0 x = -2 The two solutions are therefore, x = 3 and x = -2.
