Explanation:
Each term in the second bracket must be multiplied by each term in the first bracket. ThIs can be achieved as shown.
(color(red)(6c-1))(6c-1)(6c−1)(6c−1)
=color(red)(6c)(6c-1)color(red)(-1)(6c-1)=6c(6c−1)−1(6c−1) distributing.
=36c^2-6c-6c+1=36c2−6c−6c+1 collecting like terms.
=36c^2-12c+1=36c2−12c+1
