Answer» ong>Step-by-step explanation: = 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2) = 9x^2 - 6x + 1 - 9x^2 - 3x + 6x + 2 = -3x + 3 (3x-1)^2 - (3x-2)(3x+1) = 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2) = 9x^2 - 6x + 1 - 9x^2 - 3x + 6x + 2 = -3x + 3
If this was an equation (3x-1)^2 - (3x-2)(3x+1) = 0, in that case we can find the SOLUTION of this equation by -3x + 3 = 0 x = 1 |
