Rules of polynomials, True or False

100

True or false: You should always combine like terms.

True

200

True or false: Signs that are addition change and signs that are subtraction stay the same 

False, subtraction signs change while addition signs do not change 

300

When something is squared you must find the answer to that number that is squared first and then solve the rest of the equation, true or false?

False, you just combine like terms!

400

You always solve the first bracket and then distribute that one answer throughout the second bracket, true or false?

False, you must combine like terms from both of the brackets

500

The polynomial must always be equal on both sides to find the right answer, true or false?

False, it doesn't matter how many numbers it has as long as it has more than one polynomail
