Solve 3x(to the 3rd)+7x(squared)-22x-8=0, given that negative one third is a solution.
\n" ); document.write( "----------
\n" ); document.write( "3x^3+7x^2-22x-8=0 and x=-1/3 is a zero
\n" ); document.write( "If x=-1/3 is a zero:
\n" ); document.write( "x-1/3=0
\n" ); document.write( "3x-1 is a factor.
\n" ); document.write( "Divide the polynomial by 3x-1 to get:
\n" ); document.write( "3x^2+6x-24
\n" ); document.write( "Using the quadratic formula you get:
\n" ); document.write( "x=[-6+-sqrt(36-4*3*-24]/-6
\n" ); document.write( "x=[-6+-18]/(-6)
\n" ); document.write( "x=-2 or x=4
\n" ); document.write( "--------------
\n" ); document.write( "Final Soluition:
\n" ); document.write( "x=-1/3, x=-2, x=4
