A.
6x² + 20x - 10
B.
8x² + 24x + 10
C.
8x² + 24x - 10
D.
8x² + 16x - 10
Let's use the distributive property to expand the expression:
(2x + 5)(4x - 2)
= 2x * 4x + 2x * (-2) + 5 * 4x + 5 * (-2)
= 8x² - 4x + 20x - 10
= 8x² + 16x - 10
Therefore, the correct answer is D. 8x² + 16x - 10
(2x + 5)(4x - 2)
= 2x * 4x + 2x * (-2) + 5 * 4x + 5 * (-2)
= 8x² - 4x + 20x - 10
= 8x² + 16x - 10
Therefore, the correct answer is D. 8x² + 16x - 10
