Factoring and Simplifying Expressions

The video tutorial covers simplifying algebraic expressions by factoring. It begins with an introduction to simplifying problems, followed by a detailed explanation of factoring trinomials. The concept of the difference of squares is then discussed, and the division property is applied to simplify expressions. The lesson concludes with a recap of the key points covered.

What is the first step in simplifying algebraic expressions?

• Solving for x

• Expanding the expression

• Combining like terms

• Factoring the numerator and the denominator

When factoring the trinomial x^2 + 3x - 18, what two numbers multiply to -18 and add to 3?

• 6 and -3

• 9 and -2

• 2 and -9

• 3 and -6

What is the factored form of x^2 + 3x - 18?

• (x + 9)(x - 2)

• (x + 6)(x - 3)

• (x + 3)(x - 6)

• (x + 2)(x - 9)
