Question

if if alpha, beta and gamma are zeroes of the the polynomial p(x) = 2x^2-7x+3 , then find the value of
${ \alpha }^{3} + { \beta }^{3}$


​

Answer 1

2x²-7x+3

2x²-6x-1x+3

2x(x-3)-1(x-3)

(2x-1)(x-3)

alpha

2x-1=0

x=1/2

beta

x-3=0

x=3

alpha³+beta³=(1/2)³+3³

1/8+27

2157/8

if answer is correct mark me as brain list

Answer 2

plz answer me plz plz plz plz
