It's different to other questions where you have to prove some number is a multiple of another. There is no factor of 6 that easily pops out so its a little bit more hidden.

(a) Solve the equation giving your answer in terms of and where .
(b) Find the value of such that only one solution exists to the quadratic equation.
(c) The line with equation intersects the curve with equation .
(i) Show , by forming and solving a pair of simultaneous equations by substituting an expression for y, that
.
(ii) Find the values of such that the line is tangent to the curve .
[Hint. The tangents to intersect the curve at only one point.]

Extension questions, for bright pupils like you. They make you think very hard and very carefully about certain topics.
