Question

If alpha, beta and gama are the zeroes of the polynomial 2x³
-5x²
-14x+8, find the values of alpha +beta + gama
and Alpha * beta * gama​

Answer 1

${2x}^{3} - {5x}^{2} - 14x + 8$

we know that

$\alpha + \beta + \gamma = \frac{ - b}{a}$

$\alpha + \beta + \gamma = \frac{5}{2}$

and now

$\alpha \beta \gamma = \frac{ - d}{a}$

$\alpha \beta \gamma = \frac{ - 8}{2} = - 4$
