Question

Find a quadratic polynomial, the sum and product of whose zeroes are 8√3 and 21.​

Answer 1

Answer:

x^2-8√3x+21

Step-by-step explanation:

Given, a + b = 8√3 & ab = 21.

So the quadratic polynomial is,

x^2 - (a + b)x +ab = x^2-8√3x+21.

Answer 2

Answer:

given: sum of zeros of p(x) = 8√3 and product = 21

to find: p(x)

solution: given sum and product of polynomial,

p(x) = x² - x ( sum of zeros ) + product of zeros

=> p(x) = x² - x (8√3) + 21

=> p(x) = x² - 8√3 x + 21
