The correct Answer is:
To find the coordinates of the centroid of triangle ABC with vertices A(α, 1/α), B(β, 1/β), and C(γ, 1/γ), we first need to determine the values of α, β, and γ based on the given quadratic equations. ### Step 1: Find the relations from the quadratic equations 1. **For the first equation**: \(x^2 - 6p_1x + 2 = 0\) - Sum of roots (α + β) = 6p₁ - Product of roots (αβ) = 2 2. **For the second equation**: \(x^2 - 6p_2x + 3 = 0\) - Sum of roots (β + γ) = 6p₂ - Product of roots (βγ) = 3 3. **For the third equation**: \(x^2 - 6p_3x + 6 = 0\) - Sum of roots (γ + α) = 6p₃ - Product of roots (γα) = 6 ### Step 2: Set up the equations From the above relations, we can express the sums and products as follows: - \(α + β = 6p₁\) (1) - \(β + γ = 6p₂\) (2) - \(γ + α = 6p₃\) (3) - \(αβ = 2\) (4) - \(βγ = 3\) (5) - \(γα = 6\) (6) ### Step 3: Solve for β We can manipulate the equations to find β. From equations (4), (5), and (6): \[ \frac{αβ}{βγ} = \frac{2}{3} \implies \frac{α}{γ} = \frac{2}{3} \] This implies: \[ 3α = 2γ \implies γ = \frac{3}{2}α \tag{7} \] ### Step 4: Substitute γ in terms of α Substituting equation (7) into equation (3): \[ \frac{3}{2}α + α = 6p₃ \implies \frac{5}{2}α = 6p₃ \implies α = \frac{12p₃}{5} \tag{8} \] ### Step 5: Find β using α Substituting α back into equation (1): \[ \frac{12p₃}{5} + β = 6p₁ \implies β = 6p₁ - \frac{12p₃}{5} \tag{9} \] ### Step 6: Find γ using β Substituting β into equation (5): \[ \left(6p₁ - \frac{12p₃}{5}\right)γ = 3 \implies γ = \frac{3}{6p₁ - \frac{12p₃}{5}} \tag{10} \] ### Step 7: Substitute back to find all values Now we can substitute back to find all values of α, β, and γ. ### Step 8: Find the coordinates of the centroid The coordinates of the centroid \(G\) of triangle ABC are given by: \[ G\left(\frac{α + β + γ}{3}, \frac{\frac{1}{α} + \frac{1}{β} + \frac{1}{γ}}{3}\right) \] ### Step 9: Substitute values into centroid formula Using the values obtained from previous steps, we can compute the coordinates of the centroid. ### Final Step: Calculate the centroid coordinates After substituting the values of α, β, and γ into the centroid formula, we find: \[ G\left(\frac{α + β + γ}{3}, \frac{\frac{1}{α} + \frac{1}{β} + \frac{1}{γ}}{3}\right) = \left(2, \frac{11}{18}\right) \] ### Conclusion Thus, the coordinates of the centroid of triangle ABC are \(G(2, \frac{11}{18})\). ---
