Subtract 2x – 3x^2 + 5x^3 from 5x^3 + 4x – x^2?

Answer 1

2x – 3x^2 + 5x^3 from 5x^3 + 4x – x^2=the problem
5x^3 + 4x – x^2-(2x – 3x^2 + 5x^3)= rearrange
5x^3 + 4x – x^2-2x +3x^2 - 5x^3=distribute
5x^3-5x^3+– x^2+3x^2-2x+ 4x=rearrange
2x^2+2x=combine like terms=the answer

Answer 2

To subtract 2x – 3x^2 + 5x^3 from 5x^3 + 4x – x^2, you first need to write it out as an equation:

5x^3 + 4x – x^2 - (2x – 3x^2 + 5x^3)

First, you need to simplify. There is really a -1 that you have to multiply out to 2x – 3x^2 + 5x^3. So it becomes:

5x^3 + 4x – x^2 - 2x + 3x^2 - 5x^3

Now, look for the ones that share the same combination of variables:

[5x^3] + 4x – x^2 - 2x + 3x^2 [- 5x^3] These are the x^3 variables
5x^3 + 4x [– x^2] - 2x [+ 3x^2] - 5x^3 These are the x^2 variables
5x^3 [+ 4x] – x^2 [- 2x] + 3x^2 - 5x^3 These are the x variables


To make it easier on yourself, you can reorder the variables:

5x^3 - 5x^3 + 3x^2 – x^2 + 4x - 2x

Now, you can simply do the arithmetic. You don't need to touch the exponents. In this case, the exponents just differentiate the types of x. So x^2 might as well just be y and x^3 might as well be z. You just treat x^2 and x^3 as a separate variable from x. So, the solution is:

5x^3 - 5x^3 + 3x^2 – x^2 + 4x - 2x
0x^3 - 2x^2 + 2x
2x^2 + 2x

Hope this helps.

Answer 3

5x^3 + 4x – x^2 - (2x – 3x^2 + 5x^3) = 5x^3 + 4x – x^2 - 2x + 3x^2 - 5x^3 = 2x +2x^2 = 2x(1 + x)

Answer 4

(5x^3 + 4x – x^2)-(2x – 3x^2 + 5x^3)

=5x^3 + 4x – x^2 - 2x+3x^2 - 5x^3
=2x+2x^2
=2x(1+x) (answer)

Answer 5

you've pronounced that 243 is 3^5 and 32 is obviously 2^5, and definitely x^20 is (x^4)^5, and from there shown distinctive coefficients. Seeing you have a 5th degree polynomial in x^4, you will divide the given coefficients by using (a million,5,10,10,5,a million) and then verify out what factors stay. do not understand that there is a formula or set of policies to maintain on with, basically sturdy analytic elementary adventure.

Answer 6

2x^2 + 2x

I wish people would stop being lazy and do their own homework there is a difference between asking for help and being a slacker and having others do your work for you.
