Question 69770
Add, using the verticl method.

5x^2 + 2x - 4, x^2 - 2x - 3, and 2x^2 - 4x - 3

I am a little confused on how the verticle method is used and would appreciate any help you could offer. Thanks. 

Answer: All right. Adding the expressions is not as hard as you think it is. Seriously. It's just that you have to line it up. Watch.

{{{5x^2 + 2x - 4}}}
{{{x^2 - 2x - 3}}}
{{{2x^2 - 4x - 3}}}

Think of this as regular addition. 

Look at all of the first of the {{{x^2}}}. There is 5x^2, x^2 (which equals 1x^2) and 2x^2. So. 5 + 1 + 2 = 8. So first part is 8x^2. 

Now look at the x. There is 2x, -2x, and -4x. 2 - 2 - 4= -4. So second part is 
-4x.

Now the last part. Easy. There is -4, -3, and -3. -4 - 3 - 3= -10. So last part is -10.

Now if we combine all three together, it is 8x^2 -4x -10.Now you asked me of vertical way. Let's do it.

{{{5x^2 + 2x - 4}}}
{{{1x^2 - 2x - 3}}}
{{{2x^2 - 4x - 3}}}

{{{8x^2 - 4x - 10}}}.I really hope you get this...typing this is very difficult.
