A "+" before parentheses means + 1 times everything inside, so +(a+b-c) means +a+b-c

You have to switch the sign of all terms within the parentheses. For example, -(a - b + c - d) becomes -a + b - c + d

As there are no parentheses then the expression stated can be simplified as follows :- 7x - 4x - 9 = 3x - 9 If the parentheses were placed (7x - 4x) - 9 then the result would be the same. If the parentheses were placed 7x - (4x - 9) = 7x - 4x + 9 = 3x + 9.

Determine the GCF .If it is 1 then continue with the next step but if it is a number such as three then remove that number and divide each monomial by that number and put the polynomial within a set of parentheses with the GCF on the outside of the parentheses

Its quiet simple. All you have to know is that when you use the distributive property in math, it's most likely and equation. So you basically remove the parentheses. AKA(expanding the equation)
