Click to expand... For a quadratic equation of the form: \(\displaystyle A\cdot x^2 \, + \, B\cdot x \, + \, C \, = \, 0\) The roots are: \(\displaystyle x_{1,2} \, = \, \frac{- \, B \, \pm \sqrt{B^2 - 4\cdot A \cdot C}}{2\cdot A}\) Please show us your work and exactly where you are stuck , so that we know where to begin to help you.
