# Completed Square Form to Factorise watch

1. Use the completed square form to factorise:
6x^2 - 5x - 6

===

For the square form I got

6 (x-5/6)^2 - 61 over 36

But not sure if this is the right way to go about it ?

The way is right but the result is not
6(x-5/12)^2-6*25/144-6
Because 6(x^2-5/6 x)-6 the (5/6)x is double of first term (x) multiplied by the second term, so the second is 5/12.
