2. LCH - 2022 - P1- Q1
In this question we need to calculate a variable such that a given quadratic has just one root. We have to show that a second quadratic has no real solutions. We have to show that x=-1 is not a solution to a third quadratic. Finally, we are asked to find the remainder when a a quadratic equation is divided by a factor.
