The correct Answer is:
To solve the equations \( x^2 + 30x + 221 = 0 \) and \( y^2 - 53y + 196 = 0 \), we will follow these steps: ### Step 1: Solve for \( x \) We start with the equation: \[ x^2 + 30x + 221 = 0 \] To factor this quadratic equation, we need to express \( 30x \) as the sum of two numbers that multiply to \( 221 \). We can rewrite \( 30x \) as: \[ x^2 + 13x + 17x + 221 = 0 \] Now, we group the terms: \[ x(x + 13) + 17(x + 13) = 0 \] Factoring out the common term \( (x + 13) \): \[ (x + 13)(x + 17) = 0 \] Setting each factor to zero gives us: \[ x + 13 = 0 \quad \Rightarrow \quad x = -13 \] \[ x + 17 = 0 \quad \Rightarrow \quad x = -17 \] Thus, the solutions for \( x \) are: \[ x = -13 \quad \text{and} \quad x = -17 \] ### Step 2: Solve for \( y \) Next, we solve the equation: \[ y^2 - 53y + 196 = 0 \] To factor this quadratic equation, we need to express \( -53y \) as the sum of two numbers that multiply to \( 196 \). We can rewrite \( -53y \) as: \[ y^2 - 49y - 4y + 196 = 0 \] Now, we group the terms: \[ y(y - 49) - 4(y - 49) = 0 \] Factoring out the common term \( (y - 49) \): \[ (y - 49)(y - 4) = 0 \] Setting each factor to zero gives us: \[ y - 49 = 0 \quad \Rightarrow \quad y = 49 \] \[ y - 4 = 0 \quad \Rightarrow \quad y = 4 \] Thus, the solutions for \( y \) are: \[ y = 49 \quad \text{and} \quad y = 4 \] ### Step 3: Determine the relation between \( x \) and \( y \) Now we have the values: - \( x = -13 \) and \( x = -17 \) - \( y = 49 \) and \( y = 4 \) We can compare the values: - The largest \( x \) value is \( -13 \) and the smallest \( y \) value is \( 4 \). - Since \( -13 < 4 \) and \( -17 < 4 \), we conclude that: \[ x < y \] ### Final Conclusion The relation between \( x \) and \( y \) is: \[ x < y \]
