# Math Help - Simplification too simple?

1. ## Simplification too simple?

Alright, ive got 10 problems specifically based on Simplification. at first they were easy, simple stuff like (-5)(-w)(w)(w), but after a while it became this:

8(4-q)

(6+y)(12)

(35-10q)(-2/5)

-9(y+11)

5(3-z)-z

arent they already as simple as it gets? we had a sub today, so i couldnt ask, and its due tomorrow

to expand brackets, you take what is outside the brackets and multiply everything that is inside.

example: -2(x + 3) - 4

expand the brackets first. we take -2 and multiply everything in the brackets, so we get:

-2x - 6 - 4

now we simplify

-2x - 10

and we're done.

so you would write:

-2(x + 3) - 4 = -2x - 6 - 4
..................= -2x - 10

now do all your problems like that

3. oh yeah, forgot all about the Distribution Method lol
thanks

4. Bah, they threw one in later i didnt know about
(-8)Squared(-x)cubed would be
-64(-x) cubed
right?

as in $(-8)^2 (-x)^3$?

6. yes, but i typo'd the answer
-64(-x)Cubed

if you raise a negative number to an even power, the result is positive. if you raise a negative number to an odd power, the result is negative.

8. alright, got it all done, thanks
