Student Problem #5: Unit J Concept 5

About: This is a problem that I made up for unit J concept 5. This is a partial fraction decomposition with distinct factors and this will be helpful in Calculus for next year. To solve this problem we use algebra 2 skills to get a common denominator and do the math and simplify. Then comes the precal part with A and B. Basically we split the denominator back and put A and B on the top and find the common denominator again and solve then we identify like Ax+Bx and we look at the numerator if there is an x too and we take out the x, that is the problem you will use to plug things in. Next we get the other part like 2 and we equal it with the other numerator and solve there. We should get a= this or b= this and plug it in. Now part two with the denominator we replace a and b and we check if it is correct like the problem. 

What does the reader need to pay attention to?: The reader needs to pay attention to the steps in the picture in order to understand how to do the problem. But the reader must have prior knowledge on certain Unit J material in order to understand how to do these problems otherwise this will be confusing,
