P = -1.5t^2 + 24I
0 = -1.5I^2 + 24I
= -1.5I(I-16)
I don't get how they get -1.5I(I-16) from common factoring -1.5I. I don't see where they get the I from that is inside the brackets. -1.5I goes into 24I, -16 times right? But where does the I come from that sits right in front of it?
Thanks

What is this line "P = -1.5t^2 + 24I " doing?? ...to confuse us and you more?
0 = -1.5I^2 + 24I Choosing "l" as a letter to represent a number isn't too helpful
either; it's ALMOST as bad as letting 2 represent a general number (other than two).
If -1.5I^2 + 24I =0 then -1.5l [l -16] =0 which means l=0 or 16
