First, factor out 5:
5 (x² -x -20)

5(x-5)(x+4)
Answer: D) x = 8
Step-by-step explanation: In order to get this answer, you need to keep the 236 and add 59 evry time until you get 708.
Another thing is to multiply 59 by 8, which will give you 472. Now we add 472 and 236 and we get 708.
59 x 8 = 472 + 236 = 708.
56 + 56 + 56 + 56 + 56 + 56 + 56 + 56 = 472 + 236 = 708.
Hope this helped!
