Question

Simplify the following by collecting together like terms.

3p-4q+9p-6q+1

Answer 1

12p - 10q + 1

Explanation:

To find the answer, we add up numbers that have the same letter attached to them, since those are like terms.

Let's first add the numbers that have a p next to them.

3p + 9p = 12p

Are new expression is 12p - 4q - 6q + 1

Now let's add the numbers with q's next to them.

- 4q + -6q = -10q

Now we have the expression 12p - 10q + 1

There are no more numbers that have the same letter attached to them, so that is the simplest form it can be in.

12p - 10q + 1

Answer 2

12p-10q+1
