You can put this solution on YOUR website!
y=x^3-1 and y=-x^2 -2x -1
\n" ); document.write( "set them equal and solve for x then plug in your x and find y
\n" ); document.write( "x^3-1 =-x^2 -2x -1
\n" ); document.write( "x^3-1+x^2 +2x +1=0
\n" ); document.write( "x^3+x^2+2x =0
\n" ); document.write( "the constant=0 therefore the factor is 0
\n" ); document.write( "factor out x
\n" ); document.write( "x=0 plug in 0 and find y=-1
\n" ); document.write( "one real solution
\n" ); document.write( "x = 0, y = -1
\n" ); document.write( "x^2+x +2=0
\n" ); document.write( "solve for the two complex solutions\r
