Question

If a and B are zeroes of the quadratic polynomial x2 – X – 6, then find the values of :
i) alpha3 + Beta3
(ii) alpha4 + beta4
(iii) alpha-Beta​

Answer 1

Answer:

x^2-x-6

let alpha =a

and bet=b

a+b=1

ab=-6

roots of the eqn. are

-1+5/2,-1-5/2 these are a and b

so now u can solve by using simple addition,subtrction and multiplication
