Question

Given that √2 is a zero of the cubic polynomial 6x^3+√2x^2-10x-4√2 find its other two zeroes

Answer 1

Answer:

The other two zeros of the polynomial is

$if \alpha = \sqrt{2}$

Then

$\beta = \frac{ - \sqrt{2} + 4i}{3}$

And

$\gamma = \frac{ - \sqrt{2} - 4i}{3}$

Answer 2

Answer:

other zeroes are -2 root 2/3 and - root 2/2
