Question

2. If alfa and bita are the zeroes of the polynomial x^2 + x +2 the
find the value of 2×alfa×bita​

Answer 1

Answer: 4

Step-by-step explanation:

α and β are zeroes of the polynomial x^2+x+2.

Then equate the polynomial to 0 as-

x^2+x+2=0

Product of zeroes=Coefficient of constant / Coefficient of x^2

From the polynomial we will put values as

Product of zeroes=αβ=2/1

We need value of 2αβ so we will multiply value of αβ by 2.

αβ=2

2αβ=4
