Question

Hello need help reducing this ((x^3+x/ x^Z+X)(x^z-1/X^z+1)) please show me the steps.

Answer 1

Hoot! You just asked your first question! Hang tight while I find people to answer it for you. You can thank people who give you good answers by clicking the 'Good Answer' button on the right!

Answer 2

what is x^z?

Answer 3

it was in the problem

Answer 4

its a variable

Answer 5

then this problem cannot be factored.

Answer 6

the answer is x-1 but idk how that is

Answer 7

if z =2, then the answer is x-1

Answer 8

how did u get that?

Answer 9

substitute z = 2 and solve. you will get x-1

Answer 10

\[(x ^{3}+x) \div (x ^{2}+x) = x(x ^{2}+1) \div x(x+1) = (x ^{2}+1) \div (x+1)\]

Answer 11

\[(x ^{2}-1) \div (x ^{2}+1) = (x-1)(x+1) \div (x ^{2}+1)\]

Answer 12

multiply both, you cancel out x^2+1 and x+1, you are left with x-1

Answer 13

k let me attach the file bc i think the 2 is a z

Answer 14

ok

Answer 15

you will get the answer x-1 only if z = 2

Answer 16

does the attachment work

Answer 17

looks like a 2 to me

Answer 18

ok lol im going to re evaluate ur steps
