Solve the following equation by factorization: 15x2 - 28 = x

Question

KnowledgeBoat · Accepted Answer

Given, ⇒ 15x2 - 28 = x ⇒ 15x2 - x - 28 = 0 ⇒ 15x2 - 21x + 20x - 28 = 0 ⇒ 3x(5x - 7) + 4(5x - 7) = 0 ⇒ (5x - 7)(3x + 4) = 0 ⇒ (5x - 7) = 0 or (3x + 4) = 0 [Using Zero-product rule] ⇒ 5x = 7 or 3x = - 4 ⇒ x = or x = Hence, x = .
