Well, darling, 4x to the 2 power minus 3x minus 3 is a quadratic expression. When simplified, it becomes 4x^2 - 3x - 3. So, there you have it, honey, a sassy math lesson served up on a silver platter!
Write the quadratic equation in the form ax2 + bx + c = 0 The roots are equal if and only if b2 - 4ac = 0. The expression, b2-4ac is called the [quadratic] discriminant.

There is no simple factorisation because the quadratic expression does not have rational roots. Irrational roots are not used in factorisation.
A quadratic equation has two roots. They may be similar or dissimilar. As the highest power of a quadratic equation is 2 , there are 2 roots. Similarly, in the cubic equation, the highest power is 3, so it has three equal or unequal roots. So the highest power of an equation is the answer to the no of roots of that particular equation.

z5 is an expression, not an equation and so cannot have roots.
A rational expression is not defined whenever the denominator of the expression equals zero. These will be the roots or zeros of the denominator.
It means to have deep origins.
