Step-by-step explanation:
so im learning this rn in class and what you do is FOIL
So its stands for
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.
-4x-2+4
or -4x+4-2
Without variable they can go in any order.
