Question

If alpha beta gamma are the zeros of polynomial x cube + 2 x square - 8 x + 2 find the value of Alpha minus one plus beta minus one plus Gama minus one

Answer 1

Answer:

hope its clear

if yes please mark me

Step-by-step explanation:

α$x^{3} + 2x^{2} - 8x + 2$

it is given to find the value of α - 1 + β - 1 + γ - 1  

we an rearrange that = α + β + γ - 1 - 1 - 1

we know that  α + β + γ = -b/a

then α + β + γ - 1 - 1 - 1 = -2/1 - 1 - 1 - 1

                                    = -2 - 1 - 1 - 1  

                                    = -5
