trinomials: how do you solve x^2 - 4x + 3 ?

You don't "solve", since there is nothing to solve. Are you trying to factor the expression? Did you forget the "=0" part?

(x-___)(x-___)

Fill in the blanks with factors of 3. There is only one possibility. You cannot go wrong.
 
As tkhunny said

(x-___)(x-___)

So to solve your problem :x^2-4x+3

You need to ~

#1. seperate the X's (such as tkhunny said)

(x-___)(x-___)

#2. Now you need to find two numbers that meet these qualifications
a. Multiplied together they need to equal positive 3 (+3)
b. Added together they need to equal negative 4 (-4)

#3. After you have found those two numbers you need to plug it into
this ----> (x-___)(x-__) <------ and then you need to simplify it (multiply it out) and it needs to equal your orignal problem x^2-4x+3

EXTRA TIPS-

* Start of with the least common multiples (fyi. simple numbers)
* If you get stuck than just start writing all the numbers that multiplied together equal positive three



GOOD LUCK :) If you need anymore help feel free to ask a questions (on the board, I will be back!), PM {private message} me, or e-mail me....Tell me if you get it, again Good Luck! ~*eMmAiSkOoL242*[/quote]
