The given expression can't be factorised: factorise 8x^2-12x-6xy+9 - Wolfram|Alpha

.

I believe this is factorised... - March 10th 2010, 02:53 AMHallsofIvy
**Any**expression can be factored if you allow any numbers (irrational and/or complex) as coefficients. Mr Fantastic is correct that this cannot be factored with**integer**coefficients which is what is usually meant by "factoring". Prove It is correct that what he gives is a factoring using irrational terms. - March 10th 2010, 08:09 AMnikzbord
