  • Question
    Can (X-1)(18/X-3/2) be solved by the FOIL method?
    Community Answer
    Yes. You can't really "solve" that expression since it's not an equation, but you can use FOIL to multiply the two terms together. The fractions are multiplied like any other term.

  • Question
    What is (4y)(-y-2) - (3y)(4-y)?
    Community Answer
    That equals (-4y² - 8y) - (12y - 3y²) = -4y² - 8y -12y +3y² = -y² - 20y = -y(y + 20).
