Mastering Polynomial Addition and Subtraction

What is the first step in simplifying the given polynomial expression?

• Combine like terms

• Distribute the negative sign

• Eliminate parentheses

• Solve for x

Does distributing a positive sign change the numbers in the expression?

• No, it divides them by -1

• No, it has no effect

• Yes, it multiplies them by 1

• Yes, it turns them into their absolute values

Which operation is not necessary when simplifying the given expression?

• Distributing a positive sign

• Distributing a negative sign

• Eliminating parentheses

• Combining like terms

What effect does distributing a negative sign have on the terms 3x and -4?

• Turns 3x into -3x and -4 into +4

• Multiplies both terms by 0

• Has no effect

• Turns 3x into +3x and -4 into -4

Which term is eliminated due to the distribution of the negative sign?

• None of the above

• x to the third

• -2x squared

• 3x

After simplification, what is the coefficient of the x term?
