Answer 2

Answer:

Step-by-step explanation:

The given equation is :

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

Here, a= 1

         b= -2

         c= 3

         d= 5

α+β+γ = $\frac{-b}{a}$

          = $\frac{-(-2)}{1}$

          = $\frac{2}{1}$

          = 2

αβ+βγ+γα = $\frac{c}{a}$

                = $\frac{3}{1}$

                = 3

αβγ = $\frac{-d}{a}$

       = $\frac{-5}{1}$

       = 5
