Question

if alpha and beta are zeroes of quadratic polynomial x2+3x+6, find value of i) alpha/beta+beta/alpha ii) alpha2 + beta2​

Answer 1

Answer:

X2+3x+6

alpha+ beta=-b/a

so -3/1

alpha beta=c/a

=6

1.alpha/beta+beta/alpha

=alpha2+beta2/alpha beta

=-3*2/6

=9/6

2=alpha square +beta square

=--3*2

=9
