-48x = -2x² - x³

x³ + 2x² - 48x = 0 {added x³ and 2x² to each side}

x(x² + 2x - 48) = 0 {factored x out of left side}

x(x + 8)(x - 6) = 0 {factored the trinomial into two binomials}

x = 0 or x + 8 = 0 or x - 6 = 0 {set each factor equal to zero}

**x = 0 or x = -8 or x = 6** {solved each equation for x}
