Apply Distributive Property: Apply the distributive property (also known as the FOIL method) to multiply the two binomials (x+4) and (x−3).(x+4)(x−3)=x(x)+x(−3)+4(x)+4(−3)
Multiply Terms: Multiply each term.x(x)=x2x(−3)=−3x4(x)=4x4(−3)=−12
Combine Like Terms: Combine like terms.x2+(−3x)+4x+(−12)x2+1x−12
