|
Answer» Answer: a, b, c for each equation. (1) 2y =10 - Y2 (2) (x - 1)2 = 2 x + 3 (3) x² + 5x = -(3 - x) (4) 3m2 = 2 m² - 9 (5) P (3 + 6p) = -5 (6) x2 - 9 = 13 4. DETERMINE whether the values given against each of the quadratic equation are th roots of the equation. (1) x² + 4x - 5 =0, x= 1, - 1 (2) 2m2 - 5m = 0, m = 2, 3 5. Find k if x = 3 is a ROOT of equation kx2 - 10X + 3 = 0. 6. One of the roots of equation 5m² + 2m + k = 0 is 5. Complete the following activ to find the value of ’k”. lir a root of quadratis equation 5m2 + 2m + k = 0 |
