The equation in the problem is:
[tex]4x^2(3x^2-7x+9)[/tex]for simplify this expression we have to dristribute the 4x^2 into the parenthesis:
[tex]12x^4-7x^3+9[/tex]and now this is the shorter you can have the expression
in this case we can't use the cuadratic equation or any other algebraic expresion.
