Answer: 12x^2 - 7x -10

Step-by-step explanation:

F - First

(3x+2)(4x-5)

(3x)(4x) = 12x^2

O - Outer

(3x+2)(4x-5)

(3x)(-5) = -15x

I - Inner

(3x+2)(4x-5)

(2)(4x) = 8x

L - Last

(3x+2)(4x-5)

(2)(-5) = -10

Now put all of your answers together:

12x^2 - 15x + 8x - 10

Add the the -15x and 8x

12x^2 - 7x -10
