How Do You Factorise Polynomial Expressions?

AI Thread Summary
To factorise the polynomial expression x^3 - 2x^2 - 5x + 6, start by finding a zero, which can be guessed from the factors of 6, such as -1, 1, 2, -2, 3, -3, 6, or -6. Once a zero is identified, perform Euclidean division of the polynomial by (x - zero) to simplify it into a second-degree expression. Some participants expressed frustration with the original poster's lack of effort in solving similar problems independently. Despite this, a step-by-step approach was suggested to aid understanding. The discussion highlights the importance of engaging with the material rather than seeking direct answers.

Find a zero for your expression.
 
i am too retarded:smile: , can u show me a step by step please

Yep and you should start by "guessing a number" that is either (-1,1,2,-2,3,-3,6,-6). Why these numbers ? Well 6 can be divided by these numbers. Let's say that number is 6. Then perform an Euclidian devision in which you divide the given expression by (x - 6). What you get is an expression of second degree in x times (x-6) equals the given expression. This should get you started

Don't bother to help OP, marlon.
In another thread, he has refused even to do a single thing on his own with the expression 18t^2-2.

He is just after having his homework done for him.

Opps did not know that. Thanks for the advice, besides enough info has been given.
