Question

demonstrate how your quadratic equation expression is solved by the Quadratic Formula. Explain your steps. solve x²+x+2=0

Answer 1

The general quadratic function is\[y = a x^2 + bc +c\]For your quadratic, the a = 1, b = 1, and c = 2. Now plug them into the plug quadratic equation to find your roots.\[x = \frac {-b \pm \sqrt{b^2 - 4ac}}{2a}\]

Answer 2

Now plug them into the quadratic equation to find your roots.*
