Question

If I multiplied these binomials (x - 3) + (4x + 2) what would be the final product?

Answer 1

Answer: 4x^2 - 10x - 6

Explanation:

You can use FOIL to do this. First terms, Outer terms, Inner terms, Last terms.

(x - 3)(4x + 2)

First terms: x * 4x = 4x^2

Outer terms: x * 2 = 2x

Inner terms: -3 * 4x = -12x

Last terms: -3 * 2 = -6

Now add these together:

4x^2 + 2x - 12x - 6 = 4x^2 - 10x - 6

Answer 2

4x^2 - 10x - 6

Explanation:

If you truly want to multiply these binomials, remove the " + " sign and replace it with " * " for multiplication:

(x - 3) (4x + 2) = 4x^2 + 2x - 6 - 12x

Combining like terms, we get 4x^2 - 10x - 6
