document.write( "When using the quadratic formula to solve a quadratic equation ax2 + bx + c = 0, the discriminant is b2 - 4ac. This discriminant can be positive, zero, or negative. (When the discriminant is negative, then we have the square root of a negative number. This is called an imaginary number, sqrt(-1) = i. )\r

If b^2-4ac >0 the graph will intersect the x-axis in two points. \n" ); document.write( "For example y=x^2-4x+1 \n" ); document.write( " \n" ); document.write( "------------------- \n" ); document.write( "If b^2-4ac =0 the graph will touch but not pass through the x-axis. \n" ); document.write( "For example y=x^2-4x+4 \n" ); document.write( " \n" ); document.write( "---------------------- \n" ); document.write( "If b^2-4ac <0 the graph will be entirely above or entirely below the x axis \n" ); document.write( "For example y=x^2-4x+6 \n" ); document.write( " \n" ); document.write( "=============== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
