Question

When using FOIL to multiply the binomials (2x – 1)(–3x + 4), what is the value of the "inner" terms?

A.
–4
B.
–4x
C.
–3x
D.
3x

Answer 1

The correct option is C.

Explanation:

The given binomial expression is

`(2x-1)(-3x+4)`

The first and last term of these type of expression are know as outer terms. In this expression first and last term are x and 4.

The middle terms (second and third term) of these type of expression are know as inner terms. In this expression inner terms are -1 and -3x.

Since -3x is an inner term, therefore option C is correct.

Answer 2

Multiply the First terms in each bracket -6x2
Multiply Outer terms: inner terms =8x+3x
inner term is 3x
Multiply the Last terms in each bracket:=-4
D is the right option 3x
