Quadratic Equations:
The given equations are quadratic equations in the form ax^2 + bx + c = 0 and ay^2 + by + c = 0. We need to compare the roots of these equations, denoted by X and Y.
Finding the Roots:
To find the roots of the equation x^2 + 32x + 247 = 0, we can use the quadratic formula: x = (-b ± √(b^2 - 4ac)) / 2a. By substituting a = 1, b = 32, and c = 247 into the formula, we find the roots of this equation.
Similarly, for the equation y^2 + 20y + 91 = 0, we can find the roots using the quadratic formula with a = 1, b = 20, and c = 91.
Comparing the Roots:
After finding the roots for both equations, we can compare them to determine the relationship between X and Y.
In this case, if the roots of the equation x^2 + 32x + 247 = 0 are less than or equal to the roots of y^2 + 20y + 91 = 0, then we have X ≤ Y. Therefore, the correct answer is option 'D' which states that X is less than or equal to Y.
Conclusion:
By comparing the roots of the given quadratic equations, we can establish the relationship between X and Y. In this case, X is less than or equal to Y, as determined by the roots of the equations.
