(threex – 2)(fourx + one) =

12x² - 5x - 2

Concept:

When doing questions that need to expand algebraic expressions, using the FOIL method will ease the process:

Solve:

Given expression

(3x - 2) (4x + 1)

Expand parentheses and apply the FOIL method

First: 3x · 4x = 12x²

Outer: 3x · 1 = 3x

Inner: (-2) · 4x = -8x

Last: (-2) · 1 = -2

12x² + 3x - 8x - 2

Combine like terms

12x² + (3x - 8x) - 2

Hope this helps!! :)

step-by-step explanation:

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
