Q. Use the distributive property to multiply.(2x+5)(x2+2x−4)
Apply Distributive Property: We will apply the distributive property, also known as the FOIL method (First, Outer, Inner, Last), to multiply the binomial (2x+5) by each term in the trinomial (x2+2x−4). First, we multiply the first term of the binomial by each term of the trinomial: 2x×x2=2x32x×2x=4x22x×(−4)=−8x
Multiply Terms: Next, we multiply the second term of the binomial by each term of the trinomial:5×x2=5x25×2x=10x5×(−4)=−20
Combine Like Terms: Now, we combine like terms from the products we obtained in the previous steps: 2x3+(4x2+5x2)+(−8x+10x)−202x3+9x2+2x−20
