Question

A group consists of 12 honest People and 8 dishonest People. Write a quadrat Polynomial whose zeroes are equal to number of honest People and number of dishonest people.

Answer 1

Answer: x² + 20x + 96

Step-by-step explanation:

Number of honest people in the group = 12

Number of dishonest people in the group = 8

Now,

Let the two given values be α and β, where α = 12 and β = 8 respectively.

Now, sum of the roots = α + β

= 12 + 8

Sum of the roots = 20

And, product of the roots = α × β

= 12 × 8

Product of the roots = 96

Therefore, the quadratic polynomial will be -

p(x) = x²(Sum of the roots)x + Product of the roots

p(x) = x²(12 + 8)x + (12 × 8)

p(x) = x² = 20x + 96

The required polynomial is x² + 20x + 96
