Here, we will consider cases where the product of two quadratic polynomials results in a quartic polynomial.
Let the form of the expression be
(ax^2+bx+c)(px^2+qx+r)=k4x^4+k3x^3+k2x^2+k1x+k0.
We will expand the expression on the left-hand side into the expression on the right-hand side.
The numbers to the right of the coefficient k are subscripts, which correspond to the degree of x.
