Step-by-step explanation:
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
3/70=x/100
(3/70)*100=x
300/70=x
x=30/7=4.2857 roughly
