Answer:
Area = 6x² - 20x + 16
Explanation:
The area of a rectangle is length x width.
Plug the values into that equation:
Now you use the FOIL method to find the answer:
First: 2x × 3x = 6x²
Outer: 2x × (-4) = - 8x
Inner: (-4) × 3x = - 12x
Last: (-4) × (-4) = 16
Area = 6x² + (-8x) + (-12x) + 16
Area = 6x² - 20x + 16
