1. The problem is to evaluate the expression $x^2 + 5x$ for $x = -2$. 2. The formula given is a quadratic expression: $x^2 + 5x$. 3. Substitute $x = -2$ into the expression: $$(-2)^2 + 5(-2)$$ 4. Calculate each term: $$(-2)^2 = 4$$ $$5(-2) = -10$$ 5. Add the results: $$4 + (-10) = -6$$ 6. Therefore, the value of the expression when $x = -2$ is $-6$.
