# Find the sum and product of the roots for the following quadratic equation 3y2 – y – 4 = 0 - Mathematics

Sum

Find the sum and product of the roots for the following quadratic equation

3y2 – y – 4 = 0

#### Solution

3y2 – y – 4 = 0 ÷ 3

y^2 - y/3 - 4/3 = 0

y^2 - (1/3)y + ((-4)/3) = 0

∴ α + β = (1)/(3)

αβ = (-4)/(3)

Is there an error in this question or solution?
