Or just...
x times by x is x²
-9 times by -9 is 81
x times by -9 is -9x
and same for reverse
add -9x with -9x and you get -18x
SO basically
we are timesing by the first ( something something) by the (something something)
like...
(a+7)(8+4)
It would be
a x 8 = 8a
7 x 4 = 63
8 x 7 = 56
a x 4 = 4a
So....
4a+8a+63+56
Or if you want to simplify it
12a+63+56
Or more.
12a+109
There you go.

Okay lets see.... lets do this algebra question....
Hmmmm...
Its (x-9)(x-9)
Simple. C:
And if we try to get the answer then. Grid method.
x x -9
-9 -9x 81
x x² -9x
x²-9x-9x+81
x²-18x+81
There u go m898898
lol i am so drunk
