Question

DO ANY BODY KNOW HOW TOO ADD AND SUBARCAT POLYNOMIALS

Answer 1

Yes, you add and subtract them just like real numbers.

Answer 2

To add polynomials, you must clear the parenthesis, combine and add the like terms. In some cases you will need to remember the order of operations. Remember, when adding and subtracting like parts, the variable never changes.

Here are a couple of examples:

(5x + 7y) + (2x - 1y)

= 5x + 7y + 2x - 1y ----- (Clear the parenthesis)

=5x + 2x + 7y - 1y ----- (Combine the like terms)

= 7x + 6y --- (Add like terms)

Another Example:

(y2 - 3y + 6) + (y - 3y 2 + y3)

y2 - 3y + 6+ y - 3y2 + y3 ---- (Clear the parenthesis)

y3 + y2 - 3y2 - 3y + y + 6----- (Combine the like terms)

y3 - 2y2 - 2y + 6---- (Add like terms)

Subtracting Polynomials

To subtract polynomials, you must change the sign of terms being subtracted, clear the parenthesis, and combine the like terms. Here's an example:

(4x2 - 4) - (x2 + 4x - 4)

(4x2 - 4) + (-x2 - 4x + 4) ---- (Change the signs)

4x2 - 4 + -x2 - 4x + 4 ---- (Clear the parenthesis)

4x2 -x2 - 4x- 4 + 4 -- ----- (Combine the like terms)

3x2 - 4x

Another Example:

(5x2 + 2x +1) - ( 3x2 – 4x –2 )

5x2 + 2x +1 - 3x2 + 4x +2 --(Change the signs and clear the parenthesis)

5x2 - 3x2 + 2x+ 4x+1 + 2 --(Combine the like terms)

2x2+ 6x +3

Answer 3

-3KTO THE SECOND POWER +AK AND 11KTO THE SENCOND POWER -2K

Answer 4

$$-3k^2 +ak$$$$11k^2-2k$$

Answer 5

yep

Answer 6

can you give the problem

Answer 7

YEP WAT AND -3K TO THE THIRD POWER +4K AND 11K TO THE SECOND POWER -2K

Answer 8

Please unlock your caps :)

Answer 9

what does the and stand for

Answer 10

idk and i did it shullpartrol

Answer 11

Thank you :)

Answer 12

u welcome skull head

Answer 13

Can you type out the polynomials that you want to add?

The whole idea is to add "similar" terms.

Answer 14

wat do u mean by tht

Answer 15

you said what and -3k to the third + 4k and 11k to the 2nd power

Answer 16

yes why

Answer 17

what does that mean

Answer 18
