Answer

\( x = -8, 0 \)

Solution

Solve the equation \( x^{2}+8x=0 \). Solve the quadratic equation by following steps: - step0: Solve by factoring: \(x^{2}+8x=0\) - step1: Factor the expression: \(x\left(x+8\right)=0\) - step2: Separate into possible cases: \(\begin{align}&x=0\\&x+8=0\end{align}\) - step3: Solve the equation: \(\begin{align}&x=0\\&x=-8\end{align}\) - step4: Rewrite: \(x_{1}=-8,x_{2}=0\) The solutions to the equation \(x^{2}+8x=0\) by factoring are \(x=-8\) and \(x=0\).

Bonus Knowledge

To solve the equation \( x^{2} + 8x = 0 \) by factoring, we start by factoring out the common term \( x \): \[ x(x + 8) = 0 \] Now, we set each factor to zero: 1. \( x = 0 \) 2. \( x + 8 = 0 \) → \( x = -8 \) Thus, the solutions are \( x = 0, -8 \).
