x2+7x+6
_______
x+1

Note the line is a division sign and the x2 means X squared if ya didnt no

and also my teacher didnt no how to tell us this so i wanna figure out how to do this so i can impress him and get extra marks (want higher then 91% lol)

OH dude...

X^2 + 7x + 6 / x + 1

when you multiply 6 and 1, you get six, when you add 6 and 1, you get 7. Therefore..
(x+6)(x+1) / x+1
The X+1 cancels each other out, leaving x+6.
= x+6

the numerator is x^2+7x+6
denominator is x+1

you factor the numerator to
(x+1)(x+6)
-----------
x+1

x+1's can cancel out because you can cancel factors of the numerator with the denominator or factors of the denominator. You can only cancel whole factors of the numerator. the answer is x+6

x+6

factor the polynomial to (x+1)(x+6)
now, the (x+1)s cancel out.
