Question

Select the quadratic expression that represents the product below. -8x2 + 34x - 35 -8x2 - 34x + 35 -8x2 + 6x - 35 -8x2 - 6x + 35

Answer 1

Use the FOIL method (First, Outside, Inside, Last)

Reorder:
(2x + 5)(-4x + 7)

2x(-4x) = -8x²
2x(7) = 14x
5(-4x) = -20x
5(7) = 35

-8x² + 14x - 20x + 35

Combine like terms

-8x² (+ 14x - 20x) + 35

-8x² - 6x + 35


-8x² - 6x + 35 is your answer

hope this helps
