(x+6)(x-5)
= ( x^2 - 5x + 6x - 30 )
= x^2 + x - 30

You just have to apply the FOIL method:
1) Multiply the FIRST terms:
x * x = x²

2) Multiply the OUTER terms:
x * (-5) = -5x

3) Multiply the INNER terms:
(+6) * x = 6x

4) Multiply the LAST terms:
(+6) * (-5) = -30

Now, add them all together:

x² + (-5x) + (6x) + (-30) = x² + x - 30


That's the ONLY one I'm doing, so you better get someone else to do your homework for you. Algebra final you took on Friday? Yeah, right sweetheart.

We did that in an exam on Friday!
x^2 - 5x + 6x - 30
I think...
EDIT: Oops, didn't simplify all the way:
x^2 + x - 30

(x+6) (x-5)
= x^2-5x+6x-30
= x^2+x-30

( x + 6)(x - 5)

= x(x - 5) + 6(x - 5)

= x^2 - 5x + 6x - 30

= x^2 + x -30 (ANS)
