Biquad

In mathematics, the "square of the square" is referred to as a biquadrat , i.e. the fourth power of a number , for example . ${\displaystyle (5^{2})^{2}=5^{4}}$

Biquadratic equations are polynomial equations in which a biquadrat appears as the highest power. More specifically, it is often also required that a biquadratic equation only has even exponents: ${\displaystyle ax^{4}+cx^{2}+e=0,\quad a\neq 0}$
