Here are the solutions to the questions:
1. (i) Given that the roots of the equation 3x2−4x+2=0 are α and β.
a) Show that α3+β3=−278.
Step 1: Identify the sum and product of roots from the given quadratic equation 3x2−4x+2=0.
For ax2+bx+c=0, the sum of roots is α+β=−ab and the product of roots is αβ=ac.
Here, a=3, $
