Question

kindly help me, just want to check my ans.
FIND THE SUM:
x^2y-xy
xy^2-3xy
2x^2y-xy^2+5xy

Answer 1

you mean factor

Answer 2

you mean
\[x^2y-xy+xy^2-3xy+2x^2y-xy^2+5xy\]?

Answer 3

if so combine like terms as they say in the math biz

Answer 4

^ u prob right

Answer 5

it is x^2y-4xy+xy^2

Answer 6

ur adding the firsst two equations and the third equation is the answer then its wrong

Answer 7

\[3x^2y+xy\] i think

Answer 8

\[x ^{2}y -xy+xy ^{2}-3xy =x ^{2}y-4xy+\]

Answer 9

xy^2

Answer 10

anyone can show me the solution? because we have different answers.. i want to see where i get wrong

Answer 11

tell me what u hav to add if u hav to add the first two equations or all the three????

Answer 12

\[x^2y-xy+xy^2-3xy+2x^2y-xy^2+5xy\]
\[(x^2y+2x^2y)+(xy^2-xy^2)+(5xy-3xy-xy)\]

Answer 13

the parentheses are unnecessary i just put them there to show that i grouped "like terms" together. like terms means same variables with same exponents

Answer 14

all the 3

Answer 15

ok

Answer 16

?

Answer 17

there are three like terms yes

Answer 18

the first gives
\[3x^2y\] the second is 0, and the third is
\[xy\]

Answer 19

satellite73 how can u type the equations with exponents?

Answer 20

i am using latex

Answer 21

what is that?

Answer 22

i can't show you here because it just comes up as symbols. i can show you in chat if you like

Answer 23

see here there is a equation box there u can write equations

Answer 24

ok get it

Answer 25

thank you:)

Answer 26

welcome)

Answer 27

how about this one:
\[4x-{3+[4-(x^2-3x)+x^3]-[3x^2+(-3+4x)]+7x}\]
