The roots of a quadratic equation are -1/4 and 3. The quadratic equation is
Answer Details
We know that if a quadratic equation has roots α and β, then the equation can be written as: (x - α)(x - β) = 0 Expanding the above expression, we get: x2 - (α + β)x + αβ = 0 Here, the roots of the quadratic equation are -1/4 and 3. Therefore, α = -1/4 and β = 3. Substituting these values in the above equation, we get: x2 - (α + β)x + αβ = 0 x2 - (-1/4 + 3)x + (-1/4 × 3) = 0 x2 - 11/4 x - 3/4 = 0 Hence, the quadratic equation is 4x2 - 11x - 3 = 0. Therefore, the correct option is: 4x2 - 11x - 3 = 0
