Find a quadratic polynomial, the sum and product of whose zeroes are

$\frac{-8}{3}$ and

$\frac{4}{3}$ , respectively. Also, find its zeroes of the polynomial by factorisation.

Answer:

Quadratic polynomial

$=$

The zeroes are

and

Answer variants:

$x = -\frac{3}{2}$

$x = -\frac{2}{3}$

$x = -2$

$x^2 + \frac{8}{3}x + \frac{4}{3}$

$x^2 - \frac{8}{3}x + \frac{4}{3}$

$x = 2$
