Show that (x - 2) is a factor 3x² - x - 10. Hence, factorize 3x² - x - 10.

Question

KnowledgeBoat · Accepted Answer

By factor theorem, (x - a) is a factor of f(x), if f(a) = 0. f(x) = 3x² - x - 10 (x - 2) is a factor of f(x), if f(2) = 0 f(2) = 3(2)² - 2 - 10 = 12 - 12 = 0 Hence, x - 2 is a factor of 3x² - x - 10. Now, factorizing , Hence, 3x² - x - 10 = (x - 2)(3x + 5).
