Question
I. 3q² -29q +18 = 0 II. 9p² - 4 =
0 In each of these questions two equations numbered I and II are given. You have to solve both the equations and give answer, if –Solution
I. 3q² -29q +18 = 0 3q² - 2q – 27 q +18 = 0 ⟹ q (3q – 2) - 9 (3q- 2) = 0 ⟹ (3q - 2) (q - 9) = 0 ⟹ q= 9, 2/3 II.9p² - 4 = 0 ⟹ P² = 4/9 ⟹ p= ±2/3 ∴ p≤q
