Question

What theorems can be utilized in solving polynomials and their depressed equations?

Answer 1

n mathematics, a quartic function, is a function of the form

where a is nonzero, which is defined by a polynomial of degree four, called quartic polynomial.

Sometimes the term biquadratic is used instead of quartic, but, usually, biquadratic function refers to a quadratic function of a square (or, equivalently, to the function defined by a quartic polynomial without terms of odd degree), having the form

A quartic equation, or equation of the fourth degree, is an equation consisting in equating to zero a quartic polynomial, of the form

where a ≠ 0.

The derivative of a quartic function is a cubic function.

I am more of a problem snapper, but these theorems, not so much into....
