How is this true?? Attachment 28337

Try expanding all the brackets in the numerator and simplifying...

I did that and I got k(3k+10) ...

Is that expanding all the brackets?

yes

Surely if you still have brackets with factors outside them, then it is NOT fully expanded.

3k^2 + 10k , but it still doesn't come to what it is supposed to be.
