Step 1 of 2 :

Write down the given expression

The given expression is

525² - 475²

Step 2 of 2 :

Find the value of the expression

Use the formula a² - b² = ( a + b ) ( a - b )

Thus we get

$\sf {525}^{2} - {475}^{2}$

$\sf = (525 + 475) \times (525 - 475)$

$\sf =1000 \times 50$

$\sf = 50000$
