Answer:
[tex]\boxed{\bold{\left(3x-2\right)^2}}[/tex]
Step By Step Explanation:
Rewrite [tex]\bold{9x^2-12x+4}[/tex]
[tex]\bold{\left(3x\right)^2-2\cdot \:3x\cdot \:2+2^2}[/tex]
Rewrite Equation
[tex]\bold{\left(3x\right)^2-2\cdot \:3x\cdot \:2+2^2}[/tex]
Apply Perfect Square Formula [tex]\bold{\left(a-b\right)^2=a^2-2ab+b^2: \ a=3x,\:b=2}[/tex]
[tex]\bold{\left(3x-2\right)^2}[/tex]
