Question 329715
What do you want to do with this equation?
{{{2x^3+6x^2+3x+9}}} Factor it??
{{{(2x^2+3)(x+3)}}}
You can't solve for it x until you set the equation equal to something, like zero for example.
{{{2x^3+6x^2+3x+9 = 0}}} Solve it factoring,
{{{2x^2+3)(x+3) = 0}}} Apply the zero product rule.
{{{2x^2+3 = 0}}} or
{{{x+3 = 0}}} then...
{{{2x^2 = -3}}}--->{{{x^2 = -3/2}}}--->{{{highlight(x = sqrt(-3/2))}}} or {{{highlight(x = -sqrt(-3/2))}}}
{{{highlight(x = -3)}}} or {{{highlight(x = 3)}}}
