Remember that 
So: 
We replace on the polynomial:
To find the biggest or close number say 70 is close to 75 or 70 the answer would be 70 I think but not sure
To write it in simplest form, you must find a common factor.
In
, 3 is a factor of both 3 and 9
3÷3=1 and 9÷3=3
So
is your answer in simplest form.
