Please also remember to expand to the general case

3. Verify using a specific example that (a + b ) * (@ - b) = 2(b*@ ). Expand to the general case to prove that the result is always true. For help with this question, please check the U1A6 Assignment Question 3 video on YouTube from your instructor. Please note that the proof in the video should show that (a + b ) x (a - b) = 2(b*2 ) 4. Use a specific example to explore how the cross product behaves under scalar multiplication. Is it true that k( a * b) = (ka ) * b = a * (kj)? Expand to the general case to prove your theory
