Question
I. 8/(21x) - 2/7 = 0 II. 16y² - 24y +9 =
0 In the following questions, two equations numbered I and II are given. You have to solve both the equations and give answer.Solution
I. 8/(21x) - 2/7 = 0 ⟹ x = 2/7 × 21/8 = 3/4 II.16y² - 24y + 9 = 0 ⟹ (4y – 3)² = 0 ⟹ y = 3/4 ∴ x = y
I. 6p2 – 7p = 5p – 7p2 + 25
II. 11q2 – 63q + 90 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 4x² - 12x + 9 = 0
Equation 2: 2y² + 8y + 6 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 4x² - 12x + 9 = 0
Equation 2: 2y² + 10y + 12 = 0
I. 8y2 - 2y - 21 = 0
