Answer:
3/10
Step-by-step explanation:
The first thing that you need to do is to find the common denominator of the two fractions. The least common multiple of 2 and 5 is 10, so we can express the new equation as 15/10-12/10=3/10. Hope this helps!
<u>Step 1: Get Common Denominators </u>
<u>Step 2: Combine the two numbers together </u>
1. (a+3)(a-3) = a²+3a-3a-9 = a²-9
2. a linear equation consists of a polynomial of degree one.
