Questions: 1. A quadratic equation f(x) is such that it attains its minimumm value of-12 at x =-1 and f(1) = 4, find the sum of roots of the equation. c. 2 d. 0.5 2. Maitri & Monica try to solve a quadratic equation of the form ax2 +bx O. Maitri ends up solving with an incorrect value of 'c' & gets the roots as 5 & 2. Monica solves the equation with the wrong value of 'b' & gets the roots as -2 &-6. Find the correct quadratic equation:
