[Maths] Why don't you expand the denominator in this algebraic fraction?
Would I lose marks in the exam if I expanded the denominator:
x^2-2x-6/(x+2)(x+1)
because I was doing some My Maths revision and the final answer was the one above whereas I expanded the quadratic to get x^2+x+2x+2.
x^2-2x-6/(x+2)(x+1)
because I was doing some My Maths revision and the final answer was the one above whereas I expanded the quadratic to get x^2+x+2x+2.

In the exam, provided they see the former version, probably not. Expanding it is a waste of time and energy. Don't.

As a general rule I wouldn't bother expanding any factorised quadratics in your final solution. They prefer factorised as it's a more simple form.
Tank you all.

And you're more likely to make mistakes
