You can put this solution on YOUR website!
y = -4x^2 + 12x - 8
\n" ); document.write( "set the equation equal to 0 to get:
\n" ); document.write( "-4x^2 + 12x - 8 = 0
\n" ); document.write( "factor out a -1 to get:
\n" ); document.write( "(-1) * (4x^2 - 12x + 8) = 0
\n" ); document.write( "this allows the x^2 term to be positive which makes factoring a lot easier.
\n" ); document.write( "there are different methods to factor the quadratic equation.
\n" ); document.write( "the method of last resort is the quadratic formula that will allow you to factor any quadratic equation.
\n" ); document.write( "there are numerous references on how to factor a quadratic equation that can be of help to you there.
\n" ); document.write( "one of them can be found at the following link:

\n" ); document.write( "the factors for this particular equation are:
\n" ); document.write( "(-1) * (4x-8) * (x-1)
\n" ); document.write( "the roots of this equation are:
\n" ); document.write( "x = 2 and x = 1
\n" ); document.write( "a graph of this equation is shown below:
