Can someone please help me with the second problem?

Step-by-step explanation:

The first order of business is to get the denominator the same on both fractions. To do this change the 2nd terms denominator into intercept form. See below.

Do this for the numerator on the 2nd term also.

Now we can exclude the (x-3) from both the numerator and denominator of the second term. Now we have the equation below.

Now the denominators are the same. Now we need to exclude x+3 from both numerators. Notice that in the firt term, you do not exclude both x+3, only 1.

There is your answer

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
