let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
