Since you didn't state what the problem asked you to do, I'm going to guess that you were
asked to factor this.
.
Look for the common factors in the two terms you were given. Notice that each term has a 5
in the number portion. In one case, 10, its 5 times 2 and in the other case, 15, its 5 times 3.
Therefore we can pull a factor of 5 out. Now look at the y terms. The smallest y term that
is common to both terms is . So we can pull that out. So let's pull a factor of from the two terms and our equivalent expression is:
.
.
You can multiply these terms together to get back to the original expression. The first
multiplication is and the second multiplication is .
.
In this second part remember that because you do this type of multiplication
by adding the exponents together.
.
Hope this was what you were looking for. If not, post again and tell us what the book is
asking you to do. Most of the tutors don't have the books students are referring to,
so without a description, it's hard to guess what the exercise is.
