The sum of a number and its square is 56. Find the number. I believe its 7+49=56 but I don't know how to write it out. I must set up an Algebraic equation in order to get credit. I appreciate your help! x+8 = 0; x-7 = 0 x = -8 x = 7 So there are two solutions, not just the one you thought of. (-8)^2 + (-8) = 64 - 8 = 56 as well as yours: (7)^2 + (7) = 49 + 7 = 56 Edwin
