Finding the value of alpha square beta square of polynomial f(x)=2x^2-6x+4 when alpha and beta are zeroes.

Solution:

Given the polynomial f(x)=2x^2-6x+4

Let alpha and beta be the zeroes of the polynomial.

Therefore, by the quadratic formula, we can write:

alpha = [6 + sqrt(6^2 - 4(2)(4))]/(2(2)) = 1 + sqrt(3)

beta = [6 - sqrt(6^2 - 4(2)(4))]/(2(2)) = 1 - sqrt(3)

To find the value of alpha square beta square, we can use the following formula:

alpha square beta square = [(alpha)(beta)]^2

Substituting the values of alpha and beta, we get:

alpha square beta square = [(1 + sqrt(3))(1 - sqrt(3))]^2

= [(1^2 - 3)(1^2 - 3)]^2

= [(-2)(-2)]^2

= 4^2

= 16

Therefore, the value of alpha square beta square is 16.

Hence, the solution.
