Sum and Product of Zeroes

The sum of the zeroes of a quadratic polynomial ax² + bx + c is given by -b/a, and the product of the zeroes is given by c/a. In this problem, we are given that the sum of the zeroes is 2√3 and the product is 3.

Relationship Between Coefficients and Zeroes

We can use the relationship between the coefficients and the zeroes of a quadratic polynomial to find the polynomial. The sum of the zeroes is -b/a, and the product of the zeroes is c/a. We can write the quadratic polynomial as ax² + bx + c, where a, b, and c are constants.

Finding the Quadratic Polynomial

We are given that the sum of the zeroes is 2√3 and the product is 3. We can write the quadratic polynomial as ax² + bx + c, where a, b, and c are constants. We know that -b/a = 2√3 and c/a = 3. We can use this information to find the values of a, b, and c.
