Sure, I can provide step-by-step solutions. Here is an example: Problem: Find the roots of the quadratic equation $x^2+5x+6=0$. Solution: Step 1: Identify the coefficients $a$, $b$, and $c$ from the given quadratic equation, where $a{x}^2+bx+c=0$. In this case, $a=1$, $b=5$, and $c=6$. Step 2: Use the quadratic formula to find the roots of the equation. The quadratic formula is given by: $x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$. Substituting the values of $a$, $b$, and $c$ in the formula, we get: $x=\frac{-5\pm \sqrt{5^2-4(1)(6)}}{2(1)}$$x=\frac{-5\pm \sqrt{1}}{2}$$x_1=-3$ and $x_2=-2$ Therefore, the roots of the quadratic equation $x^2+5x+6=0$ are $-3$ and $-2$.
