Multiply the polynomials (x+3) (2x-4). What is the product in the form ax^2+bx+c?

A=

b=

c=

2*^2+2x-12

Step-by-step explanation:

Use FOIL (First outer inner last)

First

x * 2x = 2x^2

outer

-4 * x = - 4x

inner

2x * 3 = 6x

last

3 * - 4 = - 12

combine like terms

6x-4x or - 4x*6x = 2x

therefore your answer is

2x^2 + 2x - 12
