Question

show that (a-b)2 =(a+b)2 - 4ab ​

Answer 1

Answer:

Down is the proof

Step-by-step explanation:

LHS

(a-b)² = a²+b²-2ab

RHS

(a+b)² - 4ab = a²+b²+2ab-4ab

                    = a²+b²-2ab

∴LHS = RHS

Answer 2

Answer:

(a-b)² = (a+b)² - 4ab

R.H.S = (a+b)² - 4ab = a²+b²+2ab - 4ab = a²+b²-2ab = (a-b)² = L.H.S

So, (a-b)² = (a+b)² - 4ab
