17=X(X+12)
\n" ); document.write( "X^2+12X-17=0
\n" ); document.write( "USING THE QUADRATIC EQUATION WE GET:
\n" ); document.write( "X=(-12+-SQRT[12^2-4*1*-17])/2*1
\n" ); document.write( "X=(-12+-SQRT[144+68])/2
\n" ); document.write( "X=(-12+-SQRT212)/2
\n" ); document.write( "X=(-12+-14.56)/2
\n" ); document.write( "X=(-12+14.56)/2
\n" ); document.write( "X=2.56/2
\n" ); document.write( "X=1.28 SOLUTION.
\n" ); document.write( "X=(-12-14.56)/2
\n" ); document.write( "X=-26.56/2
