Expert Answer:

The name quadratic equation comes from the word, \'quad\'.
Quad means square, that is the variable getting squared - «math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«msup»«mi»x«/mi»«mn»2«/mn»«/msup»«/math»
Quadratic equation is an equation having two roots.
Therefore, quadratic equation means the equation containing the squared terms of the variable.
Quartic equation means, equation having terms of powers of 4 for the variable.
Quartic equation is also called as biquadratic equation.
And the roots of the biquadratic equation are four.
