Is it still correct / the same? (1 Viewer)

For example, if you factorise an equation and get (3x + 2)(-2x + 5), but the answer says (3x +2)(5-2x) - is it still correct [my original answer]? Considering -2 + 5 and 5-2 = positive 3.

The negative sign can be redistributed into the factor, so the factorisations are identical.

Meaning I won't lose marks no matter which way I put it?

Whether you lose marks or not, is beyond your control.

In this case, they are identical and you would not lose marks.

As for that question, you should recognise by now that a-b = -b+a, without the need for confirmation from people.

before asking such questions, why don't you expand both expressions and see if they are the same

Yes it is correct, if you right (-2x + 5) and - (5-2x). Though take care of the the negative signs as well.
