Question

if α and β are the two zeroes of the polynomial f(x)=x2 -3x+2,then find 1/α+2/β

Answer 1

Take out the roots of the equation

Answer 2

Step-by-step explanation:

x^2-3x+2

x^2-2x-1x+2

x(x-2)-1(x-2)

(x-2)(x-1)

x-2=0 | x-1=0

x=2. | x=1.

α=2

β=1

ATQ:

1/α + 1/β

1/2 + 1/1 = 1+2/2 =3/2
