Question

slove this formula by step by step plz​

Answer 1

Answer:

Step-by-step explanation:

(a-b)² = (a+b)²-4ab

a²-2ab+b² = a²+2ab+b²-4ab

a²-2ab+b² = a²-2ab+b²

∴ (a-b)² = (a-b)²

Answer 2

$\huge\underline\bold\purple{★ ANSWER :}$

Given that,

↪ (a - b)² = (a + b)² - 4ab

Let's take RHS to prove LHS

➡ (a + b)² - 4ab

➡ a² + b² + 2ab - 4ab

➡ a² + b² - 2ab = (a - b)²

$\boxed{∴ Hence\;it\;is\;proved}$
