What can I do with when brackets are there like 2(x+90) I dont get it

Hi, wizarcd.

In order to solve the
brackets in math, you can expand them.

In order to expand, you must
multiply the component outside the bracket with what is inside the
bracket.

For example, if there is 2(x+90), you can multiply 2 by x
and 90.

so the answer would be 2x+180.
