The correct Answer is:
To solve the given equations step by step, we will first address each equation separately. ### Step 1: Solve the first equation The first equation is: \[ 34x^2 + 11x - 3 = 0 \] This is a quadratic equation in the standard form \( ax^2 + bx + c = 0 \), where: - \( a = 34 \) - \( b = 11 \) - \( c = -3 \) ### Step 2: Calculate the discriminant The discriminant \( D \) is calculated using the formula: \[ D = b^2 - 4ac \] Substituting the values: \[ D = 11^2 - 4 \cdot 34 \cdot (-3) \] \[ D = 121 + 408 \] \[ D = 529 \] ### Step 3: Find the roots using the quadratic formula The roots of the equation can be found using the quadratic formula: \[ x = \frac{-b \pm \sqrt{D}}{2a} \] Substituting the values: \[ x = \frac{-11 \pm \sqrt{529}}{2 \cdot 34} \] Since \( \sqrt{529} = 23 \): \[ x = \frac{-11 \pm 23}{68} \] Calculating the two possible values for \( x \): 1. \( x_1 = \frac{-11 + 23}{68} = \frac{12}{68} = \frac{3}{17} \) 2. \( x_2 = \frac{-11 - 23}{68} = \frac{-34}{68} = -\frac{1}{2} \) ### Step 4: Solve the second equation The second equation is: \[ 51y^2 - 77y + 12 = 0 \] This is also a quadratic equation where: - \( a = 51 \) - \( b = -77 \) - \( c = 12 \) ### Step 5: Calculate the discriminant for the second equation \[ D = (-77)^2 - 4 \cdot 51 \cdot 12 \] \[ D = 5929 - 2448 \] \[ D = 3481 \] ### Step 6: Find the roots using the quadratic formula for the second equation Using the quadratic formula: \[ y = \frac{-b \pm \sqrt{D}}{2a} \] Substituting the values: \[ y = \frac{77 \pm \sqrt{3481}}{2 \cdot 51} \] Since \( \sqrt{3481} = 59 \): \[ y = \frac{77 \pm 59}{102} \] Calculating the two possible values for \( y \): 1. \( y_1 = \frac{77 + 59}{102} = \frac{136}{102} = \frac{68}{51} = \frac{4}{3} \) 2. \( y_2 = \frac{77 - 59}{102} = \frac{18}{102} = \frac{3}{17} \) ### Step 7: Compare the values of \( x \) and \( y \) From our calculations: - \( x_1 = \frac{3}{17} \) - \( x_2 = -\frac{1}{2} \) - \( y_1 = \frac{4}{3} \) - \( y_2 = \frac{3}{17} \) Now, we compare: - \( x_1 = \frac{3}{17} \) and \( y_2 = \frac{3}{17} \) (they are equal) - \( x_2 = -\frac{1}{2} \) is less than both \( y_1 \) and \( y_2 \) ### Conclusion Since \( x_1 = y_2 \), we can conclude that \( x \) is less than or equal to \( y \). ### Final Answer The answer is \( x \leq y \). ---
