Compare the strengths and weaknesses of the horizontal and vertical methods for adding and subtracting polynomials. Include comm
Pavlova-9 [17]

Answer:

Overall vertical is visually better, if done correctly

it forces you to "line up" all the common exponents.

The disadvantage is that it usually requires re-writing the problem, and it takes up space.

most problems are presented horizontally, that becomes the issue to locate the common exponents.

in both cases the biggest issue is people forget

that when subtracting "subtracting a negative is like adding a positive"

-5x - (-8x)  = 3x [that is a positive 3x]

or:

     -7x

-    - 10x

-------------

     3x

everyone misses those eventually so you have to watch out for that in both methods

Variable on both sides
IrinaK [193]

So for starts we can go 0.16 x 63 miles = 10.04 so the total for the second plan would be $58 with driving 63 miles. and for the first plan would be 0.12 divided by 3 would be 0.04 so we add them together and we get $58 with driving a 3rd of a mile.

Overall:

1st plan: $58 with driving a 3rd of a mile.

2nd plan: $58 with driving 63 miles.
