How did you get your final answer ?

vishweshshrimali5 · Answer

Upto this step you are perfectly correct:

= 2d*d/cd + 2c*c/dc

anonymous · Answer

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

vishweshshrimali5 · Answer

$$\large{\cfrac{2d^2}{cd} + \cfrac{2c^2}{cd}}$$

After this ?

anonymous · Answer

Yes, it was the step before last

vishweshshrimali5 · Answer

Okay after this you should get this:

$$\large{=\cfrac{2c^2+2d^2}{cd}}$$

$$\large{=\cfrac{2(c^2+d^2)}{cd}}$$

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