    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

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

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

    well to complete the table you need to finish the multiplications...this is the grid method for factoring or multiplying |dw:1438052784629:dw| use the infomration

    |dw:1438052874483:dw| you need to find n x ?? = n^2 5 x ? = 40 they are the missing bits

    \[n^2 + 40n + 13 = (n + 8)(n + 5)\]
