Understanding Squaring Expressions

The video tutorial explains how to correctly square the expression 2x. It emphasizes that squaring a term involves squaring both the coefficient and the variable, leading to the result a^2 = 4x^2. Two methods are presented: multiplying the term by itself and applying the exponent to each part of the term separately. Both methods yield the same result, reinforcing the concept of squaring in algebra.

What is the correct interpretation of a^2 when AAL 2x?

• a^2 = 4x^2

• a^2 = 2x^2

• a^2 = 2x

• a^2 = x^2

In the first method of evaluation, what is the result of a^2?

• a^2 = 2x^2

• a^2 = 4x^2

• a^2 = 8x^2

• a^2 = x^2

How many factors of 2x are considered in the first method?

• Four

• Three

• Two

• One

In the second method, what is the value of 2^2?

• 8

• 6

• 4

• 2

What is the final result of a^2 using the second method?

• a^2 = 2x^2

• a^2 = 4x^2

• a^2 = 8x^2

• a^2 = x^2
