Answer 3

Solving the Equation x² + y², given x + y = 5 and xy = 6

To solve the equation x² + y², given x + y = 5 and xy = 6, we can use the following approach:

1. Using the Given Equations: We have the following two equations: - x + y = 5 - xy = 6

2. Finding the Values of x and y: We can solve for the values of x and y by substituting the value of y from the first equation into the second equation to solve for x.

3. Substitution: Let's solve for y in terms of x from the first equation: y = 5 - x

Now, substitute this value of y into the second equation: x(5 - x) = 6

Simplifying the equation: 5x - x² = 6 Rearranging the terms: x² - 5x + 6 = 0

4. Finding the Values of x and y: We can solve for the values of x using the quadratic formula: x = (-b ± √(b² - 4ac)) / (2a)

where a = 1, b = -5, and c = 6.

By solving for x, we can then find the corresponding values of y.

5. Calculating the Values of x and y: By applying the quadratic formula, we can find the values of x and then calculate the corresponding values of y.

6. Final Solution: Once we have the values of x and y, we can substitute them back into the expression x² + y² to find the solution.
