Find the values of a and b where a<3 so thatA² - 5A - 21 = 0, where I is2 Web13 feb. 2024 · Let us calculate ( A − B) ( A + B) as follows using the fact that the matrix product is distributive. ( A − B) ( A + B) = A ( A + B) − B ( A + B) = A 2 + A B − B A − B 2 = A 2 − B 2 + ( A B − B A). Thus if ( A − B) ( A + B) = A 2 − B 2 then A B − B A = O, the zero matrix. Equivalently, A B = B A. female shih tzu for adoption

WebIf a + b = 10 and ab = 21, find the value of a 3 + b 3. Solution: a + b = 10, ab = 21 Cubing both sides, (a + b) 3 = (10) 3 ⇒ a 3 + 6 3 + 3ab (a + b) = 1000 ⇒ a 3 + b 3 + 3 x 21 x 10 = 1000 ⇒ a 3 + b 3 + 630 = 1000 ⇒ a 3 + b 3 = 1000 – 630 = 370 ∴ a 3 + b 3 = 370 Question 3.
