proof THAT

(n+1)² - n² = 2n + 1 ​

Answer 1

Answer:

$\huge\boxed{\bf \implies: 0}$

Step-by-step explanation:

$\bf(n+1)² - n² = 2n + 1 \\ \\ \bf\implies: {n}^{2} + 2n + 1 - {n}^{2} = 2n + 1 \\ \\ \bf\implies: \cancel{{n}^{2} } \: \: \: \: \cancel{+ 2n} \: \: \: \: \cancel{+ 1} \: \: \: \: \cancel{ - {n}^{2} } \: \: \: \: \cancel{- 2n} \: \: \: \: \: \cancel{ - 1} \\ \\ \huge\boxed{\bf \implies: 0}$
