How do you form a quadratic equation from this?
\n" ); document.write( "If x=-3 and x=4, then form a quadratic equation.
\n" ); document.write( ":
\n" ); document.write( "If you know how to factor a quadratic equation, then reverse the process:
\n" ); document.write( "x = -3 and x = 4, gives us factors of
\n" ); document.write( "(x+3)(x-4) = 0
\n" ); document.write( "FOIL
\n" ); document.write( "x^2 - 4x + 3x - 12 = 0
\n" ); document.write( "so we have:
\n" ); document.write( "y = x^2 - x - 12
\n" ); document.write( "
\n" ); document.write( "
