You can put this solution on YOUR website!
y= x^2 + 4x - 1
\n" ); document.write( "Answer:
\n" ); document.write( "If x=0, then y=-1
\n" ); document.write( "If y=0, we get a quadratic equation,
\n" ); document.write( "x^2 + 4x - 1=0
\n" ); document.write( "Solve for x, using quadratic formula
\n" ); document.write( " x = (-b +- sqrt( b^2-4*a*c ))/(2*a)
\n" ); document.write( "You'll get the x intercept.
\n" ); document.write( "
\n" );
