Algebra introducing equations

The video tutorial covers the FOIL method for multiplying binomials, explaining how to expand expressions like (X + Y)^2. It introduces three special quadratic equations that are commonly tested on the SAT, emphasizing memorization to save time. The tutorial then shifts to functions, demystifying function notation and providing strategies for solving function problems on the SAT. The video reassures students that these problems are often simpler than they appear and encourages practice to build confidence.

What is the result of applying the FOIL method to (X + Y)^2?

• 2X^2 + 2Y^2

• X^2 + Y^2

• X^2 + XY + Y^2

• X^2 + 2XY + Y^2

Which of the following is a special quadratic equation?

• X^2 - Y^2

• X^2 - 2XY + Y^2

• X^2 + 2XY + Y^2

• All of the above
