so im learning this rn in class and what you do is FOIL

First

Outside

Inside

Last

(3x+6)(x+7)

(3x+6)(x+7) -- 3x² (if you have x times x it is x to the second power)

(3x+6)(x+7) -- 21x

(3x+6)(x+7) -- 6x

(3x+6)(x+7) -- 42

Now add 21x and 6x

27x +42+ 3x²

you must have added the 21 and 6 incorrectly.
