Question

Find (z^)+2z-5)-(9z-3z^2). Write your answer in standard form.

Answer 1

To find (z^2+2z-5)-(9z-3z^2) and write the answer in standard form, we need to simplify the expression by combining like terms.

First, let's distribute the negative sign to the terms in the second parenthesis:

(z^2 + 2z - 5) - (9z - 3z^2)

= z^2 + 2z - 5 - 9z + 3z^2

Next, let's combine like terms. We have z^2 and 3z^2, so we can add them together:

(z^2 + 3z^2) + 2z - 5 - 9z

= 4z^2 + 2z - 5 - 9z

Now, let's combine the terms with z:

2z - 9z

= -7z

Putting it all together, the simplified expression in standard form is:

4z^2 - 7z - 5

Therefore, the answer to the expression (z^2+2z-5)-(9z-3z^2) in standard form is 4z^2 - 7z - 5.
