Apply Distributive Property: Apply the distributive property (also known as the FOIL method for binomials) to multiply the two binomials (2x−4) and (2x−6). First, multiply the first terms in each binomial: (2x)⋅(2x)=4x2.
Multiply First Terms: Multiply the outer terms in the binomials: (2x)⋅(−6)=−12x.
Multiply Outer Terms: Multiply the inner terms in the binomials: (−4)×(2x)=−8x.
Multiply Inner Terms: Multiply the last terms in each binomial: (−4)×(−6)=24.
Multiply Last Terms: Combine the like terms from the products of the outer and inner terms: −12x−8x=−20x.
Combine Like Terms: Add all the products together to form the trinomial: 4x2−20x+24.
