$\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$ this is the quadratic formula
\n" ); document.write( " $\"ax%5E2%2Bbx%2Bc=0\"$ find a,b, and c in $\"3x%5E2-x-2=0\"$
\n" ); document.write( "a=3
\n" ); document.write( "b=-1
\n" ); document.write( "c=-2
\n" ); document.write( "Plug values into the equation and solve
\n" ); document.write( " $\"x+=+%28-%28-1%29+%2B-+sqrt%28+-1%5E2-4%283%29%28-2%29+%29%29%2F%282%2A3%29+\"$ Simplify
\n" ); document.write( " $\"x+=+%281+%2B-+sqrt%2825%29%29%2F%286%29+\"$
\n" ); document.write( " $\"x+=+%281+%2B-+5%29%2F%286%29+\"$
