Select the correct product.

(x 2 + 4x + 8)(2x - 1)

Step-by-step explanation:

Use FOIL: (a + b)(c + d) = ac + ad + bc + bd

The correct answer

(x² + 4x + 8)(2x - 1) = 2x³ + 7x² + 12x - 8  

Step-by-step explanation:

It is given that, (x² + 4x + 8)(2x - 1)

Points to remember

xᵃ * xᵇ = xᵃ⁺ᵇ

To find the product

(x² + 4x + 8)(2x - 1) = [(x²*2x) + (4x *2x) (8*2x)] - [x² + 4x + 8]

 = 2x³ + 8x² + 16x - x² - 4x -8

 = 2x³ + 8x² - x² + 16x - 4x -8  

 = 2x³ + 7x² + 12x - 8
