Question

Multiply using the FOIL method: (2x + 3)(x − 4)

A. 2x^2 − 11x − 12

B. 2x^2 + 11x − 12

C. 2x^2 + 5x − 12

D. 2x^2 − 5x − 12

Answer 1

D.

Explanation:

(2x + 3)(x - 4)

2x^2 - 8x + 3x - 12

2x^2 - 5x - 12

Answer 2

Answer: option d

Explanation:

In order to simplify this, we are going to use a technique called FOIL.

FOIL stands for:

• first
• outside
• inside
• last

Simplify:

`\sf{(2x+3)(x-4)}`

`\sf{2x*x-2x*4+3*x+3*(-4)}`

`\sf{2x^2-8x+3x-12}`

`\sf{2x^2-5x-12}`

Therefore, the answer is option d.
