Let y represent the number Let ^2 represent square(power of 2). 3 x y - 25 = y^2 - 35 3y - 25 = y^2 - 35 move the terms at the left to the right y^2 - 3y - 35 + 25 =0 y^2 - 3y - 10 = 0 y^2 - 5y + 2y - 10 =0 y(y - 5) + 2(y - 5) =0 (y - 5) (y + 2) = 0 if y - 5 = 0, then y = 5.. or if y + 2 = 0, then y = - 2.. Thus, y is either 5, or -2. You can take this to the bank! |
