Solve for {eq}x {/eq}: {eq}x^2 - 4x + 1 = 0 {/eq}.

Question:

Solve for {eq}x {/eq}: {eq}x^2 - 4x + 1 = 0 {/eq}.

Solve a Quadratic equation:

We are given a quadratic equation and we need to compute the values of the unknown variable. If possible, we can factor the quadratic equation. Otherwise, we can use the quadratic formula.

For a quadratic equation of the form {eq}a x^2+b x+c=0 {/eq}, the solutions are {eq}x= \dfrac{-b \pm \sqrt{b^2-4ac}}{2a} {/eq}.
