STEP Q - got it right, but is it right?
OK STEP I 2004 question 3 (ii) asks you to factorise 6y^3-y^2-21y+2x^2+12x-4xy+x^2y-5xy^2+10 into 3 linear factors. I did it all and got the factors as:
(y+2)(3y-x-5)(2y-x-1) which is right however in the answers they have:
(y+2)(x-3y+5)(x-2y+1) it's the same thing basically, but will I get the marks for writing it in my form? -

Of course you will. They're equivalent.
