Let's take an example to illustrate this case:
<span>positive fraction = 2/7
</span>
<span>negative fraction = - 3/5
Now we need to subtract </span><span>- 3/5 from 2/7
Right?
2/7 - (-3/5) = 2/7 + 3/5
here we need to unify the denominators as follows:
the lowest common factor between 7 and 5 is 35
2/7 = 10/35
3/5 = 21/35
Now back to </span><span>2/7 + 3/5:
</span><span><span>2/7 + 3/5 = 10/35 + 21/35 = (10+21)/35 = 31/35
That's it
Hope that helps you</span>

Answer: (b) square root of 3
Step-by-step explanation:
Factor the numerator and factor the denominator.
Then you divide the numerator and the denominator by the common factor to reduce the fraction.
-1+ 5 i think I dont know
b^2-4ac<0 b^2-144<0 (b-12)(b+12)<0
-12<b<12
