If alpha and beta are the zeroes ofthe quadratic polynomial f(x)=x2-x-...
X² - x -4 is the given quadratic equation.

Given, alpha and beta are zeroes of the given equation.

we know, sum of zeroes = -b/a
alpha + beta = 1

and

product of zeroes = c/a
alpha × beta = -4

To find, :-

1/alpha 1/beta - alpha × beta

by putting values

1/-4 +4 => 15/4

If alpha and beta are the zeroes ofthe quadratic polynomial f(x)=x2-x-...
Solution:

Given:
- Quadratic polynomial: f(x) = x^2 - x - 4
- Zeroes: α, β

Formulas:
- Sum of zeroes: α + β = -(-1) = 1
- Product of zeroes: αβ = -4

Value to find:
1/α + 1/β - αβ

Calculation:
- We know that 1/α + 1/β = (α + β) / (αβ) = 1 / (-4) = -1/4
- Therefore, 1/α + 1/β - αβ = -1/4 - (-4) = -1/4 + 4 = 15/4

Therefore, the value of 1/α + 1/β - αβ is 15/4.
