Apply Distributive Property: Apply the distributive property (also known as the FOIL method) to multiply the two binomials (3x−9) and (3x−3).(3x−9)(3x−3)=3x(3x)+3x(−3)−9(3x)−9(−3)
Multiply Terms: Multiply the terms.3x(3x)=9x23x(−3)=−9x−9(3x)=−27x−9(−3)=27
Combine Like Terms: Combine like terms.9x2−9x−27x+279x2−36x+27
