C + c - 14a + 15bm - 13a - 17bm
rearrange
c + c - 14a - 13a + 15bm - 17bm
combine like terms
2c - 27a - 2bm
And got my Math paper 4 IGCSE external tomorrow, thanks for posting this question that helped me more!
You can factor out a 3t first, resulting in:

Now, let's factor the equation in the middle using the quadratic equation. Plug in the values to the quadratic equation:

Simplify, you get your
