Hello i just need some help with proving that $(A+B)^2 = A^2 +2AB + B^2$ holds for commutative matrices. This is only equal to A2 + 2AB + B2 when AB = −BA, which in general is not true. Expand by multiplying each term in the first expression by each term in the second expression.snoitulos pets-yb-pets htiw revlos htam eerf ruo gnisu smelborp htam ruoy evloS . Now Type the Following Code to the Python idle. (A + B)2 = A2 + 2AB + B2 (A + B)2 = A2 + AB + BA + B2. My thought process: Since it is not a proof, I figure I can show by example and come to a valid conclusion based on such example. (a - b)^2 Break down the expression into a simpler form by regrouping and … 2a2-2ab-2b2 Final result : 2 • (a2 - ab - b2) Step by step solution : Step 1 :Equation at the end of step 1 : ((2 • (a2)) - 2ab) - 2b2 Step 2 :Equation at the end of step 2 : (2a2 - 2ab) - … Assume that A and B are both n × n matrices, how would I prove that (A + B)2 =A2 + 2AB +B2 for any n × n matrices?
