Question

Divide and simplify completely. Assume that no denominator equals zero. d^2-1/d^2-d divided by d - 1/d

Answer 1

@UnkleRhaukus

Answer 2

\[\frac{d^2-1}{d^2-d}\div\frac{d-1}d\\
=\frac{d^2-1}{d^2-d}\times\frac d{d-1}\\
=\]

Answer 3

factor the denominator of the first fraction . . .

Answer 4

d^2 @UnkleRhaukus

Answer 5

huh?

Answer 6

d^2 - 1/d^2

Answer 7

what is that susposed to be?

Answer 8

the answer

Answer 9

its not right

Answer 10

ok

Answer 11

factor the numerator and denominator of \(\dfrac{d^2-1}{d^2-d}\)

Answer 12

wouldn't the top be the same and the bottom be d^2?

Answer 13

@UnkleRhaukus

Answer 14

nope

Answer 15

hmmm well then i am not sure :/ @UnkleRhaukus

Answer 16

can you factor


d^2 - d ?

Answer 17

(d^2 -d) (d^2 + d)

Answer 18

d^2 - d = d*d - d
= d(d-1)

Answer 19

oh

Answer 20

d^2-1 = (d-1)(d+1)

Answer 21

what do i do next?

Answer 22

@UnkleRhaukus

Answer 23

\[\frac{d^2-1}{d^2-d}\div\frac{d-1}d\\
=\frac{d^2-1}{d^2-d}\times\frac d{d-1}\\
=\frac{(d-1)(d+1)}{d(d-1)}\times\frac{d}{d-1}\\
=\]

Answer 24

d + 1 / d - 1?

Answer 25

yep

Answer 26

Thank you
