Question

If alpha and beta are the zeroes of a quadratic polynomial 3x^2 +2x -6, then find the value of alpha cube beta square + alpha square beta cube... Pls answer me fast

Answer 1

Answer:

∝+β=-2/3 and ∝β=-6/3=2

ask that ∝³β²+∝²β³

=(∝β)²∝+(∝β)²β

=(∝β)²(∝+β)........................................................eq(1)

∝+β=-2/3 and ∝β≈-2 puting in eq(1)

=(-2)²×(-2/3)

=-8/3
