this has to be one of the goofiest questions tonight
i guess you are supposed to figure that one of the factors is $n+5$ from that table

lokiando · Answer

I am not a math geek

anonymous · Answer

the question is, what is the other factor
since the last number is 40 then the missing number must be 8 right? since $5\times 8=40$

anonymous · Answer

with questions like this it is clear than no one is expecting to create a math geek for sure

anonymous · Answer

seems like the they are trying to create mind readers
go with 
$$(x+5)(x+8)$$

lokiando · Answer

well the table seems to be uncomplete, thats my opinion

campbell_st · Answer

well to complete the table you need to finish the multiplications...this is the grid method for factoring or multiplying

you need to find    n x ?? = n^2

5 x ? = 40

they are the missing bits
