Question

If -1 and 2 are zeroes of polynomial 2x^3-x^2-5x-2. Find its another 0

Answer 1

Hey here is your answer.


If alpha =-1

Bita = 2


Then,

Sum of the zeroes: alpha + bita
=-1+2 = 1.

Product of the zeroes: alpha ×bita
=-1 × 2= -2

Now forming the equation

X^2 - (1) x + (- 2)

X^2 - X - 2.
