You can put this solution on YOUR website! Hello,
The first trick is to set all these {2 + 5w-7v/7w - 8w-v/3w} to fractions with the same denominator as follows:
42w/21w + 105w^2/21w - 21v/21w - 168w^2/21w - 7v/21w
Now we can rewrite this as:
(-63w^2 +42w-28v)/21w
Rewritten as:
7(-9w^2+6w-4v)/21w
This reduces to:
(-9w^2+6w-4v)/3w
Did you follow this?
