Same for me it won’t let me pick a certain topic
2x² - 4x - 30
2(x²) - 2(4x) - 2(15)
2(x² - 4x - 15)
1. 4.374
2. 52.64
3. 840.5
You get 8 if you round up from 8.041451517
and 8 cubed is 512
but if you round from 8.041451517 to 8.04, and you cube it, it equals 519.718464
and if you round that up it would equal 520
or 519.71
so it depends on how you do it
