=48n^2 -18n -3=48n218n3

Explanation:

color(blue)((8n+1))(6n-3)(8n+1)(6n3)
Here, both the terms of color(blue)((8n+1)(8n+1) need to be multiplied with both of the terms of (6n-3)(6n3)

=color(blue)((8n))(6n) +color(blue)((8n))(-3) + color(blue)(1)(6n)+ color(blue)(1)(-3)=(8n)(6n)+(8n)(3)+1(6n)+1(3)

=48n^2 -24n +6n-3=48n224n+6n3

=48n^2 -18n -3=48n218n3
