Question

if alpha and beta are zeros of the polynomial p(x)=3x-2x-6,then find Alpha Cube + beta cube

Answer 1

Answer:

I am taking

alpha=A & beta=B

Since, p(x) = 3x-2x-6

= x-6

A+B = -b/a

= -(1) /0

= -1/0

=0

AB = c/a

= -6/0

= 0

Therefore,

A^3 + B^3 = (A+B)^3 - 3AB(A+B)

= (0) ^3 - 3(0) (0)

= 0-3(0)

= 0
