Question

find the HCF and LCM of x-1,x^2-1,x^2-x+xy-y

Answer 1

do you have numbers for x and y?

Answer 2

there is no number dats just it

Answer 3

(x-1)

(x^2-1) <-- can be factored

x^2-x+xy-y <-- can be factored

can you factor them @getexcool ?

Answer 4

yap i can

Answer 5

roit that makse sense do that ^

Answer 6

tell me what you get o:

Answer 7

i got (x-1)(x+1)

Answer 8

dats for x^2-1

Answer 9

yup

Answer 10

wat about for X^2-x+xy-y i cant factor it @nphuongsun93

Answer 11

\[x^2-x+xy - y\]take the common x and common y
\[x(x-1)+y(x-1)\]take the common (x-1)
\[(x+y)(x-1)\]

Answer 12

(x-1)

(x-1)(x+1)

(x-1)(x+y)

do you know how to find these?
LCM and HCF~

Answer 13

yap it is quiet clear now
