If alpha and beta are the zeroes of the polynomial f(x) = ax 2 + bx + c, then evaluate
1)alpha2+ beta2
2)alpha/beta + beta/alpha
3)alpha3+ beta3
4)1/alpha3+ 1/beta3
5)alpha2/beta + beta2/alpha
please help mee...
expert again don't post the similar question link the one u posted earlier was not at all the answer :(

f(x) = ax² + bx + c
(1) alpha² + beta²
= (alpha+beta)² - 2alphabeta
= (-b/a)² - 2c/a
=-(b²+2ac)/a²
(1) alpha² + beta²
= (alpha+beta)² - 2alphabeta
= (-b/a)² - 2c/a
=-(b²+2ac)/a²
