Question

(x-3√2)(x+3√2) what will be the answer..plz write me the correct answer

Answer 1

(x-3√2)(x+3√2)

x^2-(3√2)^2

Ans-x^2-18

Answer 2

Here is your answer

By using this identity

you can easily solve this

a²-b²= (a+b)(a-b)

where a= x

and

b= 3√2

Now using this identity of a²-b²

= x²-(3√2)²

= x²-18

x²= 18

x= +3√2

or

x = -3√2

Hope this helps you
