00:00hi guys in this video we are going to discuss that how to factorize algebraic expression
00:06with very easy method from zero so we have an algebraic expression 3x squared minus 9xy
00:15and we have to factorize it factorization simply mean we have to convert this subtraction of
00:23two algebraic expression into the multiplication so first of all simple step is that you have to
00:29convert each term into product of its simplest factor for example we have first term 3x squared
00:35so we can write 3x squared as 3 times x times x so this is converted into product of simplest factors
00:44then we move to second we have negative sign so we put negative sign and 9 can be factorized by
00:50parameterization so we can write 3 times 3 so this is a product of 9 and then we have two variables
00:57x times y so in the next step you have to identify common factors so you can see that and 3 is common
01:06to both terms and also x is common to both terms so after writing common factors we can write uncommon
01:17factors so after writing common factors we have to put bracket so these common factors are done here
01:24in both terms so now you can see that we are left with no uncommon factors we have only one uncommon
01:30factor in first term that is x then a sign of subtraction then we have two factors 3 and y in second term
01:39so x minus 3y so 3x into x minus 3y is factorized form of given expression 3x squared minus 9xy
