Question

please help @saifoo.khan ....this is exactly wht the problem said also
add : (5x^2y + 3x^2 + 4) + (2x^2y+4x)

Answer 1

just combine the like terms
like 5x^2y+2x^27
andthen rewrite it

Answer 2

whoops, my bad the 7 is supposed to be a y

Answer 3

combine like terms ? i thought u can only do that if it said combine them

Answer 4

(5x^2y + 3x^2 + 4) + (2x^2y+4x)

Get rid of parenthesis first.

5x^2y + 3x^2 + 4 + 2x^2y + 4x

Now, arrange.. (like terms)

5x^2y + 2x^2y + 3x^2 + 4x + 4

Now as you can see that ONLY the first two terms have same variables with same exponents so we can add their number.

So,

7x^2y + 3x^2 + 4x + 4

Answer 5

\[(8x^4 + 3x^3 - 1) - (4x^2 - 3x + 5)\]what if there are mixed operations within the problem ? do i still arrange them like tht....for example,

Answer 6

yes.. it makes the prob easier.

Answer 7

ok becuz i actually thought u were supposed to solve the problem but pretty much im just collecting like terms and simplifying the problem correct

Answer 8

Totally correct.

Answer 9

and tht first problem, i didnt even have the entire problem wrote lol thts probably y it didnt make too much sense

Answer 10

Yes. right. ;)

Answer 11

\[(-9a^5b^4+7a^3b^3=2a^2b^2)+(2a^4b^4-5a^3b^3-a^2b^2)\]

Answer 12

There's a mistake! D:
you wrote an equal sign.. that must be + ?

Answer 13

minus, im sorry ;-)

Answer 14

My browser crashed. i almost typed everything. -_-

Answer 15

\[(−9a^5b^4+7a^3b^3-2a^2b^2)+(2a^4b^4−5a^3b^3−a^2b^2)\]
arrange,
\[\large -9a^5b^4 + 2a^4b^4 + 7a^3b^3 - 2a^3b^2 - 5a^3b^3 - a^3b^3\]Now add like terms.

Answer 16

\[-9a^5b^4 + 2a^4b^4 + (7-2-5-1)a^3b^3\]
\[\large -9a^5b^4 + 2a^4b^4 + -1a^3b^3\]

Answer 17

\[\large -9a^5b^4 + 2a^4b^4 - a^3b^3\]
