(x+8)(x-1)=0 x+8=0 x=-8 x-1=0 x=1 Therefore, the zeroes are -8 and 1.
Just take the parenthesis and you will have your answer.
Numerically, if the question looks like this:--(3a + 7b) - 8a - 4b + 2Then the answer is this:--3a - 7b - 8a - 4b + 2= -11a -11b + 2
Minus 8 plus 6 equals -2.

To solve (184 + 243 + 808) - (109 + 72 + 84) evaluate the parentheses first: (184 + 243 + 808) - (109 + 72 + 84) = 1235 - 265 = 970
The System folder is installed as part of the operating system at the top level of the hard disc. If you have more than one hard disc attached to the Mac hold down the Option (alt) key when the Mac starts up - this will open the Start Up Manager which enables you to switch the start up to another disc with a system folder.
