a. To solve x + 5x = 0, Mai rewrote the equation as x(x + 5) = 0. Explain how rewriting this equation in factored form enables Mai to solve the equation. 7. b. Solve 3x2 = 6x by rewriting the equation. Show your reasoning. c. Explain why dividing each side of 3x? = 6x by 3x is not a reliable way to solve the equation.
