It factors to (x-5) (x+4) so the solutions are 5 and -4.

If so, what you could you could factor it into: (x+5)(x-4), they multiply to -20 and add up to a positive 1

Given the equation x2 - x - 20 = 0, we see that it can likely be factored easily. Through simple trial and error we find that: (x - 5)(x + 4) = 0. From here, we set both terms equal to zero to find all possible solutions. x - 5 = 0 x = 5 and x + 4 = 0 x = -4. Substituting 5 and -4 back into the original equation yield true results. Thus the solution set is x = -4, 5. More formal, the solution set is {-4, 5}. Note: There are other methods of solving this problem such as the quadratic formula or by graphing the function.
