It should be -3(x-4) because the negative sign will also be distributed so it will be equal to -3x+12 which is what is in the original equation.

You made a mistake in grouping the terms here: (x² - 4x) - (3x +12) = 0

You should've included the negative sign for 3x: (x² - 4x) + (-3x +12) = 0 or changed +12 to -12 since you initially factored out the - sign: (x² - 4x) - (3x -12) = 0 Any of these two would've given you the right answer :)

If you used -3(x+4), that will be equal to -3x -12, which is not similar to the equation.

Btw, i like how you factor :) It's different from how a typical high school student does it

How different? Hahaha I thought it was like a normal way. Anyway thanks!

Shall I explain more? Well, a lot would just think of two factors that would satisfy the equation, without doing grouping and factoring out, like what you did. :D

so it's like the others have no process or anything?

or does mine come out a bit immature?

No not immature. I find this method easier and more systematic, although to use it one needs to understand the concept behind the method. I think you really understand how math works, if you know what i mean.
