The correct Answer is:
To find a quadratic polynomial given the sum and product of its zeroes, we can follow these steps: ### Step 1: Identify the sum and product of the zeroes We are given: - Sum of the zeroes (α + β) = \( \frac{5}{3} \) - Product of the zeroes (αβ) = 2 ### Step 2: Use the standard form of a quadratic polynomial The standard form of a quadratic polynomial with zeroes α and β can be expressed as: \[ P(x) = x^2 - (α + β)x + (αβ) \] ### Step 3: Substitute the values of sum and product into the polynomial Substituting the values we have: \[ P(x) = x^2 - \left(\frac{5}{3}\right)x + 2 \] ### Step 4: Eliminate the fraction by multiplying through by 3 To eliminate the fraction, we can multiply the entire equation by 3: \[ 3P(x) = 3\left(x^2 - \left(\frac{5}{3}\right)x + 2\right) \] This simplifies to: \[ 3P(x) = 3x^2 - 5x + 6 \] ### Step 5: Write the final polynomial Thus, the quadratic polynomial we are looking for is: \[ P(x) = 3x^2 - 5x + 6 \] ### Summary The quadratic polynomial with the given sum and product of zeroes is: \[ P(x) = 3x^2 - 5x + 6 \] ---
