Solve by Factoring x^3+3x^2-4x-12=0
Group the first two terms and the last two terms.
Factor out the greatest common factor (GCF) from each group.
Factor the polynomial by factoring out the greatest common factor, .
Rewrite as .
Since both terms are perfect squares, factor using the difference of squares formula, where and .
Remove unnecessary parentheses.
If any individual factor on the left side of the equation is equal to , the entire expression will be equal to .
Set the first factor equal to .
Subtract from both sides of the equation.
Set the next factor equal to .
Subtract from both sides of the equation.
Set the next factor equal to .
Add to both sides of the equation.
The final solution is all the values that make true.
