Question

Simplify 2c^-1 d + 2d^-1 c

= 2d/c + 2c/d

= 2d*d/cd + 2c*c/dc

Final Answer: 4d^2 c^2/cd

Is it correct?

Answer 1

How did you get your final answer ?

Answer 2

Upto this step you are perfectly correct:

= 2d*d/cd + 2c*c/dc

Answer 3

Well the step before last is: 2d^2/cd + 2c^2/cd

Answer 4

\[\large{\cfrac{2d^2}{cd} + \cfrac{2c^2}{cd}}\]

After this ?

Answer 5

Yes, it was the step before last

Answer 6

Okay after this you should get this:

\[\large{=\cfrac{2c^2+2d^2}{cd}}\]

\[\large{=\cfrac{2(c^2+d^2)}{cd}}\]

Answer 7

Wait. I guess I shouldn't have added 2d^2 and 2c^2 since they're not like terms

Answer 8

Correct ! You got it ^^^

Answer 9

Ok! Gotta pay closer attention I guess. Thank you!

Answer 10

Your welcome.
