WebIf 2a + 3b = 7 and ab = 2, find 4a 2 + 9b 2. Expansions ICSE. 3 Likes. Answer. We know that, a 2 + b 2 = (a + b) 2 - 2ab. ∴ 4a 2 + 9b 2 = (2a) 2 + (3b) 2 = (2a + 3b) 2 - 12ab. Substituting values we get, ⇒ 4a 2 + 9b 2 = (7) 2 - 12 × 2. ⇒ 4a 2 + 9b 2 = 49 - 24. ⇒ 4a 2 + 9b 2 = 25. Hence, 4a 2 + 9b 2 = 25. Answered By. 3 Likes. Related ...
