The rule in /mathemtics, when no brackets are given, is DO THE MULTIPLCATUION/DIVISION before addition /subtraction.
You calculator is programmed this way.
Hence
-3 -2 X 4 = -3 - 8 = -11
Notice I have made the mukltiplication be forde the subtraction.
However, if the sum is wrtitten as (-3-2)x 4 , then you do the brackets first .
( -5) x 4 = -20
It is definitely NOT -6 x 4

X2 plus 1 divided by 2x4 plus 4x3 -x2 plus 4x-3?
You can work this out with long division, by checking to see if (x2 - 1) is a factor of (2x4 + 4x3 - x2 + 4x - 3). It is. Unfortunately, the WikiAnswers system is somewhat limited in depicting things such as long division, so we won't be able to represent it here. In short though, (2x4 + 4x3 - x2 + 4x - 3) / (x2 + 1) is equal to 2x2 + 4x - 3. which means that: (x2 + 1) / (2x4 + 4x3 - x2 + 4x - 3) = (x2 + 1) / (x2 + 1)(2x2 + 4x - 3) = 1 / (2x2 + 4x - 3)
