A term can be a signed number, a variable, or a constant multiplied by a variable or variables. Each term in an algebraic expression is separated by a + sign or J sign. ... When a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.
We have the equation:

So then we need to distribute -7p to the parentheses:

Then we need to set the equation equal to 0, so we must subtract 21 on both sides:

Then we need to factor this. So we end up with:

This is as much as this can be factored, so <u>we cannot go any further</u>.
