Question

6. If alpha and Beta are the zeroes of the polynomial f(x) = x ^ 2 - x -4. Find the value of 1/alpha + 1/beta - alpha*beta ​

Answer 1

Answer:

polynomial f(x) = x ^ 2 - x -4 then

α + β = -(-b/a)

= -(-1/1)

= 1

αβ = c/a

= -4/1

= -4

1/α + 1/β -αβ

α + β/αβ - αβ

1/-4 -4

-1/4 -4

-1/4 - 4x4/1x4

-1-16/4

-17/5
