Calculate the discriminant \(\Delta = b^2 - 4ac\) by substituting the values: \(\Delta = (-4)^2 - 4 \times 4 \times 1\).
Evaluate the square root of the discriminant: \(\sqrt{\Delta}\).
Substitute \(b\), \(\sqrt{\Delta}\), and \(a\) into the quadratic formula to find the two solutions: \(x = \frac{-(-4) \pm \sqrt{\Delta}}{2 \times 4}\).
