Factor by grouping.
24x^2 - 20x + 30x - 25

(24x + 5)(x - 5)
(4x - 5)(6x + 5)
(24x - 5)(x + 5)
(4x + 5)(6x - 5)

First add the like terms to simplify:
24x^2+10x-25
(6x-5)(4x+5)
It looks right, what do you think?

24xÂ² - 20x + 30x - 25 = 0

(24xÂ² - 20x) + (30x - 25) = 0

4x(6x - 5) + 5(6x - 5) = 0

(4x + 5)(6x - 5) = 0
