Question

simplify (x+5) (x-5)
​

Answer 1

Answer:

It's answer is x square -5 square

Answer 2

Answer:

answer is ( x² – 5²)

Step-by-step explanation:

(x+5)(x–5)

= x(x–5) +5(x–5)

= (x²–5x) +(5x –25)

= x²–5x + 5x – 25 .......( opening brackets)

= x²– 25.........( here –5x and 5x will get cancelled)

= x² – √25........( we want to simplify it and get the both values as squares)

therefore,

= x² – 5²

therefore,

(x+5)(x–5) = x² –5²
