|
Answer» Step-by-step solution Dividing by 3 , x² - 2/3x - 8/3 = 0 x² - 2/3x + (2/3 × 1/2)² - (2/3 ×1/2)² - 8/3 = 0 x² - 2/3x + (2/6)²- (2/6)² - 8/3 = 0 x² - 2/3 x + 4/36 - 4/36 - 8/3 = 0 x² - 2/3 x + 4/36 = 4/36 + 8/3 (x - 2/6)² = 4/36 + 8/3 (x - 2/6)² = 25/9 (x - 2/6) = √(25/9) x - 2/6 = 5/3 x = 5/3 + 2/6 x = 10/6 + 2/6 ∴ x = 12/6 = 2 x = 2 Pls. mark me as brainliest... |
