The correct Answer is:
To find a quadratic polynomial with the given sum and product of its zeroes, we can follow these steps: ### Step 1: Identify the sum and product of the zeroes The sum of the zeroes (α + β) is given as \(-\frac{1}{4}\) and the product of the zeroes (αβ) is given as \(\frac{1}{4}\). ### Step 2: Use the standard form of a quadratic polynomial The standard form of a quadratic polynomial based on the sum and product of its zeroes is given by: \[ P(x) = x^2 - (α + β)x + (αβ) \] Substituting the values of the sum and product into this formula, we get: \[ P(x) = x^2 - \left(-\frac{1}{4}\right)x + \frac{1}{4} \] ### Step 3: Simplify the polynomial This simplifies to: \[ P(x) = x^2 + \frac{1}{4}x + \frac{1}{4} \] ### Step 4: Eliminate fractions by multiplying by a common denominator To eliminate the fractions, we can multiply the entire polynomial by 4 (the least common multiple of the denominators): \[ 4P(x) = 4\left(x^2 + \frac{1}{4}x + \frac{1}{4}\right) \] Distributing the 4 gives: \[ 4P(x) = 4x^2 + x + 1 \] ### Step 5: Write the final polynomial Thus, the quadratic polynomial we are looking for is: \[ P(x) = 4x^2 + x + 1 \] ### Summary The quadratic polynomial with the given sum and product of its zeroes is: \[ \boxed{4x^2 + x + 1} \]
