Question

Amrit and Pankaj expanded (x − 5 )², Amrit's answer is (x² − 25) and Pankaj's answer is x² − 10 x + 25. which of the following statement is correct?​

Answer 1

Answer:

(a-b)²= a²-2ab+b²

so expanding (x-5)²

we get, x²-10x+25

So, Pankaj's answer is correct

Answer 2

By using formula (a - b)² = a² - 2ab + b²

(x - 5)² = x × x - 2 × x × (-5) + (-5)²

(x - 5)² = x² - 10x + 25 .

pankaj's answer is correct ....
