Sample Flashcards

Expand (x + 2)(x + 5)
x² + 5x + 2x + 10 = x² + 7x + 10 (Using FOIL: First + Outer + Inner + Last)
Expand (x + 6)(x - 4)
x² - 4x + 6x - 24 = x² + 2x - 24 (Be careful with negative signs!)

Sample Questions

Expand (x + 5)².

  • A. x² + 25
  • B. x² + 5x + 25
  • C. x² + 10x + 25
  • D. x² + 10x + 5
