Answer:

(x +  11 ) * ( x - 11)

Step-by-step explanation:

The expression:

x²   -    121

is a difference of squares

We notice that     √x²    =  x       and    √121    =   11

Then

( x²  -  121  )  =   ( x + 11 ) *  ( x  -  11 )

If we multiply

( x  +  11 ) *  ( x  -  11 )   =    x*x  - 11*x  +  11*x  - (11)*(11)

( x  +  11 ) *  ( x  -  11 )   =  x²  - 121

That is what we want to probe
