Question

Find the zeroes of the quadratic polynomial 62 − 3 − 7 and verify the relationship between the zeroes and the

coefficients.​

Answer 1

Answer:

Answer

k = ± 9.69

Given

α and β are the zeroes of quadratic polynomial x² - kx + 15

such that  ( α² + β² ) - 2αβ = 34 .

To Find

Value of k

Solution

Given quadratic polynomial is x² - kx + 15

Compare given equation with ax² + bx + c , we get ,

a = 1 , b = - k , c = 15

Also given α , β are zeroes of the quadratic equation .
