Hey!

To solve this equation, we'd first have to apply the distributing rule to this equation.

Original Equation :
$( 3a - 2 )^{2}$

New Equation {Changed by Applying the Distribution Rule} :
$( 3a )^{2} - 2$ · 3a · 2 + $2 ^{2}$

And now we simplify.

Old Equation :
$( 3a ) ^{2} -2$ · 3a · 2 + $2 ^{2}$

New Equation {Old Equation Simplified} :
$9a ^{2}$ - 12a + 4

So, the equation $(3a - 2) ^{2}$ simplified is $9a ^{2}$ - 12a + 4.

Hope this helps!
