First, u lay out the numbers u have. z ^2+ z + 4z^3+4z^2
Now look at some rules. In order to combine these, they have to be same letter same power. These are not so the answer is gonna be the same thing. It is the equation. U can’t simplify it further.
Change 1 1/2 into a improper fraction. then multiply across. so 2 times 3 over 7 times 2. which equals 6/14. then simplify to get 3/7 as your final answer.
