okay

dan815 · Answer

start factoring

anonymous · Answer

okay lol

dan815 · Answer

check the first derivative, see where the critical points are at,

dan815 · Answer

so you get a feel for where u shud look

anonymous · Answer

oohh okay hold on i'm kinda slow lol

anonymous · Answer

wait doesn't the 1 go on the top of the formula for the factoring method?

anonymous · Answer

if so then i don't think you can factor that...

|dw:1415167458763:dw| this is how i was taught to factor

anonymous · Answer

If you don't know how to factor it, you could try synthetic division if you know how. It's much easier for polynomial equations.
