Simplifying Square Roots and Expressions

The video tutorial addresses a challenging math problem involving the simplification of a square root. It begins by breaking down the number four into its factors and manipulating them under the square root. The tutorial then demonstrates how to rewrite numbers to form a perfect square trinomial, which is factored and simplified. Finally, the video compares the decimal forms of the original and simplified expressions to verify the correctness of the solution.

What is the first step in simplifying the given square root in the video?

• Expressing four as 3 * 1

• Expressing four as 2 * 2

• Expressing four as 2 * 3

• Expressing four as 4 * 1

What is the result of moving one factor of two under the square root with a three?

• It becomes a six

• It becomes a five

• It becomes a four

• It becomes a seven
