Answer:
(6, -7)
Step-by-step explanation:
Rewriting x^2+x-30=12 in standard form for a quadratic equation yields
x^2+x-42 = 0. This, in turn, can be factored: (x+7)(x-6) = 0.
Here the product of these two factors is zero.
Solving x+7=0 for x, we get x= - 7; solving x-6 for x, we get x = 6.
The solutions are {6, -7).
