\( = \frac { - 2 \pm \sqrt { 20 } } { 4 } \)

Let’s simplify that expression a bit! The square root of 20 can be simplified to \( \sqrt{4 \times 5} = 2\sqrt{5} \). So, the expression becomes: \[ = \frac{-2 \pm 2\sqrt{5}}{4} \] Now, factoring out a 2 from the numerator gives us: \[ = \frac{2(-1 \pm \sqrt{5})}{4} = \frac{-1 \pm \sqrt{5}}{2} \] So the final simplified solution can be expressed as: \[ x = \frac{-1 + \sqrt{5}}{2} \quad \text{or} \quad x = \frac{-1 - \sqrt{5}}{2} \] Now you have two potential solutions!
