Multiply fist and last. Factor out to equal middle. Then group
3xy+9x-2y-6 howw would i factor by grouping cant figure it out
This question is about factoring polynomials by grouping, and I am confused on how to solve this problem. Hope you will help me as soon as possible.
factorise each of the following expressions completely a) 6x^2y^2-5xy-4 b) 3z-8xyz+4x^2y^2z c) 36y^2-49(x+1)^2
In problems like 2x^2+3n-9 I keep getting x(x+6)-3(x-3) but don't know if its right or where to go from there.

How do you complete the factoring 8y^2-6y=2y
The question is 8ax-2a+4bx-b
x3+4x2+x+4 (x3+4x2)+(x+4) x2(x+4)+(x+4) ? x+4 is the common factor but i'm not understanding how to factor out from here.
Introduction To Factoring A composite number is a number that can be written as the product of two positive integers other than 1 and the number itself. For example: 14 is a composite number because it can be written as 7 times 2. In this case, 7 and 2 are called factors of 14. A composite expression is similar in that it can be written as the product of two or more expressions. For example:... read more
