Question

p(x)= x²-5x+6 have two zeros alfa nad bita, find out the 1)1/α+1/β 2) α²+β² 3)α³+β³​

Answer 1

Answer:

Two Methods: If α & β are zeroes of f(x) =x²-x-2 then α + β = -b/a = 1 α β ... If α, β, γ are zeros of cubic polynomial x³ + 5 x - 2, what is the value of α³ + β³ + ... Also we have α² β² =( α β)² = (3)²=9 ... From given equation [math]\alpha+\beta=3[/math].
