Simplifying Expressions and Operations

The video tutorial explains how to simplify algebraic expressions by combining like terms and performing basic operations. It covers simplifying 2x - x to x, combining terms in 2 + x + x to get 2 + 2x, and multiplying terms in 2 * x * x to obtain 2 * x^2. The tutorial emphasizes understanding the concept of like terms and the correct application of basic algebraic operations.

What does the expression 2x - x simplify to?

• 2x

• 0

• x

• 2

What is the first step in simplifying 2x - x?

• Add the coefficients

• Subtract the coefficients

• Multiply the coefficients

• Divide the coefficients

What is the simplified form of 2x - x?

• 0

• 2x

• 2

• x

Why is it incorrect to say 2x - x = 2?

• Because x is not a number

• Because 2x - x simplifies to x

• Because subtraction is not allowed

• Because it should be 2x - x = 0

What is a common mistake when simplifying 2x - x?

• Multiplying the coefficients

• Adding the coefficients

• Leaving the expression unchanged

• Subtracting incorrectly

If you have two apples and take away one, how many apples are left?

• Three apples
