Question

if alpha and beta are the zeros of polynomial 3x square + 2x - 6 then find the value of a square alpha square plus beta square​

Answer 1

Answer:

40/9

Step-by-step explanation:

3x² + 2x - 6 = 0

Let α and β Be the zeroes of the equation.

a=3, b = 2, c = -6.

α + β = -b/a = 2/3 = 2/3

αβ = c/a = -6/3 = -2

α² + β² = (α + β)² - 2αβ

            = (2/3)² - 2(-2)

            = 4/9 + 4

            = 40/9
