Question

If alpha and beta are the zeroes of the polynomial 3x2+8x+2=0 then find the value of
1} alpha2+beta2
2} alpha3+beta3
3} alpha2-beta2



urgent plz.....!!!

Answer 1

Answer:

ecuación es 3x² + 8x + 2

Al comparar esta ecuación,

a = 3, b = 8, c = 2

suma de ceros = -b / a

alfa + beta = -8/3

producto de ceros = c / a

alpha × beta = 2/3

alpha ² + beta² = (alpha + beta) ² - 2alpha × beta

(-8/3) ² - 2 × 2/3

64/9 - 4/3

52/9
