Question

(x+2)(x+1)=e^x find x

Answer 1

lol good luck with that program

Answer 2

what methods are you allowed to use?

Answer 3

anything

Answer 4

can you use numerical methods like Newton's?

Answer 5

anything is fine, just if it gives you an precise anwer

Answer 6

in that case just rearrange your equation as:\[f(x)=e^x-(x+1)(x+2)=0\]and use Newton's method to find all the roots.

See here for a definition of this method: http://en.wikipedia.org/wiki/Newton%27s_method

Answer 7

Ok thanks alot! I will figure it out. Are there also other possibilities solving this one? I'm interested in knowing them all
