    2. The roots of the quadratic $a x^2 + b x + c$ are given by $$\frac{-b \pm \sqrt{b^2-4ac}}{2a}$$ If $b^2-4ac <0$, the quadratic has no real roots. Write a function to calculate the real roots of a quadratic. The function should have 3 arguments, *a*, *b* and *c*. If $b^2-4ac <0$, the function should print "quadratic has no real roots", and then return(NULL). Otherwise, the function should return a vector of length 2, those being the real roots (which...
