Evaluating determinants involving variables(Hinglish)| Determinants | Grade 12 | Math | Khan Academy

From the creator

In this video, we practice evaluating determinants of matrices with variable elements. We apply algebraic identities to simplify the determinants. For the first problem, we use square of sum identity and for the second one we use cube of sum identity. Courses on Khan Academy are always 100% free. Start practicing—and saving your progress—now!
