How would you factorise:

6t^2 - 13t + 6

This is not specialist mathematics.

But...

6t^2 - 4t - 9t + 6

2t(3t-2)   -3(3t-2)

(2t-3)(3t-2)

Needed for queston I encountered in the essentials specialist book and I couldn't do.

I forgot how to factorise by grouping.

Thank you.

You could have just used your CAS, or if you forget just complete the square! :P
