if alpha and beta are the zeros of the polynomial 2x^2-4x+5 then find the values of
The general solution to the equation
is, using the quadratic formula:
From there, expand α²+β² to get (b²-2ac)/a²
I will leave parts (ii) to (iv) for you as practice.
(iv)a^-1=1/a similarly 1/2
tried my best to answer hope its correct:)
