Question

Multiply: (x + 3)(x – 4) What is the middle term in the simplified product? x –x 3x -4x

Answer 1

-x

This is because when you distribute, you get a -4x and a 3x. Then you simplify them to get -x

Answer 2

-x is the middle term

Explanation:

Expanding the function (x + 3)(x – 4)

= x(x)-4x+3x-3(4)

= x²-4x+3x+12

= x²-x+12

This gives the simplified form of the expansion.

In the resulting equation, the middle term is -x
