dude:
Between 1 and 10?
Allison:
Yeah not sure why it copies as 101
Allison:
-x^2+7x+14
dude:
Formatting dw \(-(1)^2+7(1)+14\) <-- this should be ez \(=-(10)^2+7(10)+14\)
Allison:

Allison:
So 19 and 61... 1 and 10
dude:
No no 20 and -16 But same idea \(\dfrac{-16-20}{10-1}\)
Allison:
Where you get those from? My calculator says 19 and 64
dude:
\(=-(1)^2+7(1)+14\) \(-1+7+14=20\) ~~~~~~~~~ \(=-(10)^2+7(10)+14\) \(-100+70+14\) \(-30+14=-16\)
