Question

3xsquare-4x+1 then alphacube-betacube

Answer 1

Answer:

1/3, 1

Step-by-step explanation:

3x2 - 3x -x+1

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

Answer 2

Answer:

= given equation is a quadratic equation so we can find its roots ,say alpha and beta by factorization method

= 3x^2-4x+1

3x^2-3-x+1

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

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

(3x-1)(x-1)

3x-1=0. ;x-1=0

3x=1. ;x-1=0

x=1/3 ;x=1and

= alpha=1/3 ;beta =1

hece ,as per question

(1/3)^3-(1)^3

1/27-1

1-27/27

= -26/27 ans.
