Question
Solve the quadratic equations and determine the
relation between x and y: Equation 1: 21x² - 122x + 160 = 0 Equation 2: 23y² - 159y + 270 = 0Solution
For Equation 1: (21x - 80)(x - 2) = 0, x = 80/21 or x = 2. For Equation 2: (23y - 90)(y - 3) = 0, y = 90/23 or y = 3. Comparison: x = 80/21 > y = 3. x = 2 < y = 3 Answer: E) x = y or no relation
