Using Foil Method In (3x-7)(4x+9), Which Of The Following Is The Product Of The Outer Terms ?, A.-63

Using FOIL Method in (3x-7)(4x+9), which of the following is the product of the outer terms ?

a.-63
b.12x
c.-28x
d,27x

 

Answer:

D. 27x

Step-by-step explanation:

Using FOIL Method:

F = (3x)(4x) = 12x²

O = (3x)(9) = 27x

I = (-7)(4x) = -28x

L = (-7)(9) = -63

The product on outer terms is 27x.
