Quizplus · Accepted Answer

This cubic equation can be simplified by factoring out an $x$, resulting in $x(x^2 - 3x - 18) = 0$. Factoring further, we get $x(x-6)(x+3) = 0$, which gives the roots $x = 0$, $x = 6$, and $x = -3$.

Solve the Equation x3=3x2+18xx ^ { 3 } = 3 x ^ { 2 } + 18 xx3=3x2+18x

Solve the Equation $x ^ { 3 } = 3 x ^ { 2 } + 18 x$
