Solving Quadratic Equations
Quadratic Equation | Factor | Roots |
---|---|---|
x² - 6x = 0 | x(x - 6) = 0 | x = 0, 6 |
3x² - 12x = 0 | 3x(x - 4) = 0 | x = 0, 4 |
x² - 7x + 12 = 0 | (x - 4)(x - 3) = 0 | X = 4, 3 |
x² - 2x - 15 = 0 | (x - 5)(x + 3) = 0 | x = 5, -3 |
x² + 6x + 5= 0 | (x + 5)(x + 1) = 0 | x = -5, -1 |
x² - 16x = -64 | (x - 8)(x - 8) = 0 | x = 8 |
7x² - 49x = 0 | 7x(x - 7) = 0 | x = 0, 7 |
x² - 11x = -28 | (x - 7)(x - 4) = 0 | x = 7, 4 |
x² - 8x - 20 = 0 | (x - 10)(x + 2) = 0 | x = 10, -2 |
8x² + 32x = 0 | 8x(x + 4) = 0 | x = 0, -4 |
