ALGEBRA
  • Rules:
  • Only LIKE TERMS may be added or subtracted
  • When multiplying or dividing, use exponent laws
  • Distributive Property:
  • a(b+c) = axb + axc
examples
Examples
  • 1. x(x + 5) + 2(x – 7)
  • 2. 4x(x – 9) – (x – 10)
equations the danlad procedure
EQUATIONS: The DANLAD Procedure
  • D – Distributive Property
  • A – Add like terms on each side
  • N – Numbers on right side
  • L– Letters on left side
  • A – Add like terms on each side
  • D – Divide by the coefficient in front of the variable
examples2
Examples:
  • 1. 6(5k – 8) – 20 = 11(2k-3) + 3k
  • 2. -4(3 – 6d) = 9(2d – 2)
