Activity: Griling with Foil
Given below are expressions in factored form in which both factors are binomials. Follow the process in multiplying the binomials using FOIL method and answer the questions that follow. Write your answer on your answer sheet.
1. (x + 1)(x + 2) = x2 + 2x + x + 2
= x2 + 3x + 2
2. (x-2)(x-3) =x2 – 3x - 2x + 6
= x2 - 5x + 6
3. (x + 3)(x-4) = x2 - 4x + 3x - 12
= x² - x - 12
