Question 31041
Solve:
{{{x^3+3x^2-x-3 = 0}}} Factor.
{{{(x^2-1)(x+3) = 0}}} Factor the left parentheses.
{{{(x+1)(x-1)(x+3) = 0}}} Apply the zero products principle.
{{{x+1 = 0}}} and/or{{{x-1 = 0}}} and/or{{{x+3 = 0}}}
If {{{x+1 = 0}}} then {{{x = -1}}}
If {{{x-1 = 0}}} then {{{x = 1}}}
If {{{x+3 = 0}}} then {{{x = -3}}}

The roots are:
x = -1
x = 1
x = -3
