correct Option is B i.e, $72x^2+288x^2-216x$ whose simplified form is: $360x^2-216x$

Step-by-step explanation:

We need to solve the expression:

$2[(6x)(6x)]+4[(12x - 9)(6x)]$

Solving:

$2[(6x)(6x)]+4[(12x - 9)(6x)]\\=2[36x^2]+4[(12x*6x)-(9*6x)]\\=72x^2+4[72x^2-54x]\\=72x^2+288x^2-216x\\=360x^2-216x$

So, correct Option is B i.e, $72x^2+288x^2-216x$ whose simplified form is: $360x^2-216x$
