The formula to find the roots of a quadratic equation is: x = [-b ± sqrt(b^2 - 4ac)] / 2a. Use this formula to calculate the roots. For example, if a = 1, b = -5, and c = 6, the return values should be {3, 2}. 1 2 3 pair<double, double> findRoots(int a, in...

For the other solution of x = −10.39 we have (−10.39)2 + 103.9 − 4 = 0.05, which, because of the rounding used to limit the number of decimal places in determining the root, is effectively zero. The quadratic formula Consider the quadratic equation ax2 + bx + c = 0. To ...
