Question

if alpha, beeta,gamma are the zeroes of the polynomial p of x=x3+3x2-5x+1 find the value of 1 /alpha+1/beeta+1/gamma​

Answer 1

Step-by-step explanation:

taking LCM

$\frac{ \alpha + \beta + \gamma }{ \alpha \beta \gamma } \: \: \: \: \: \: \: 1$

we know ,sum of roots = -b/a = -3

product of roots=-d/a = (-1)

put in 1

-3/-1
