# Find a quadratic polynomial each with the given numbers as the sum and product of its zeroes respectively. √2 , 1/3 - Mathematics

Find a quadratic polynomial each with the given numbers as the sum and product of its zeroes respectively.

sqrt2 , 1/3

#### Solution

sqrt2, 1/3

Let the polynomial be ax2 + bx + c, and its zeroes be α and ß

Given α + ß = sqrt2 = (-b)/a

αß = 1/3 = c/a

If a = 3, then b = sqrt2 and  c = 1/3

Therefore, the quadratic polynomial is 3x2 - 3sqrt2 x +1.
