Answer 2

25 × 25 - 2 × 25 × 25 + 25 × 25 = 0

Given : 25 × 25 - 2 × 25 × 25 + 25 × 25

To find : The value

Formula : ( a - b )² = a² - 2ab + b²

Solution :

Step 1 of 2 :

Write down the given expression

The given expression is

25 × 25 - 2 × 25 × 25 + 25 × 25

Step 2 of 2 :

Find the value

Use the identity ( a - b )² = a² - 2ab + b²

25 × 25 - 2 × 25 × 25 + 25 × 25

$\sf = {25}^{2} - 2 \times 25 \times 25 + {25}^{2}$

$\sf = {(25 - 25)}^{2}$

$\sf = {(0)}^{2}$

$\sf = 0$
