What is the exact value of the other root?
Lostsunrise [7]

The exact value of the other root to the quadratic equation is x = -2 - \sqrt 6

<h3>How to express the solution?</h3>

One of the root is given as:

x = -2 - \sqrt 6

As a general rule, the solution to a quadratic equation is represented by:

x =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}

This means that the actual root of the given root is:

x = -2 \pm \sqrt 6

Split the equation

x = -2 - \sqrt 6 and x = -2 + \sqrt 6

Hence, the exact value of the other root to the quadratic equation is x = -2 - \sqrt 6
