Re: Factorization

Hi;

That is a quadratic expression and when it is set to 0 we can sometimes factor it easily to get the roots.


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: Factorization

A quadratic equation is a second degree equation and the general form is

ax^2 + bx + c = 0

I am guessing this is what you are after. Please post the question as it was given to you.

Re: Factorization

Zeeshan 01 i would reccomend you to read every topic on Quadratic Equations in mif. Here's the link:http://www.mathsisfun.com/algebra/index-2.html

It is very much needed in mathematics and itwill be very useful to u if you learn it.

Re: Factorization

Ok I know it well but I want to low about how roots make equal equations

Re: Factorization

That is because of the degree of the polynomial. A polynomial with degree 2 will have 2 roots. Similarly a polynomial with degree 9 will have 9 roots. If you want to know why this happens, it is because of the +,- signs.

have 2 solutions
. The degree determines the no. of roots.

Not necessarily: some of the roots may be the same root.  Take
, for instance. The degree only determines the maximum number of unique roots.

Also,

Re: Factorization

Yes, it has: when you factorize it you get :

and when you get the polynomial =0 then you get the 2 roots
.
