Find the values of a, b, c and d if

Question

KnowledgeBoat · Accepted Answer

Given By definition of equality of matrices, we get d = 3, 5 + c = -1 or c = -6, a + b = 6 [...Eq 1], ab = 8 [...Eq 2]. Putting value of b from Eq 1 in Eq 2, Now, finding value of b = 6 - a, if, a = 2, b = 6 - 2 = 4. or, a = 4, b = 6 - 4 = 2. ∴ a = 2 or 4, b = 4 or 2, c = -6 and d = 3. Hence, the values are a = 2, b = 4, c = -6, d = 3 OR a = 4, b = 2, c = -6, d = 3.
