anonymous · Answer

$$9x^2-6x+1$$ is a perfect square
what do you think it is the square of?

anonymous · Answer

just make a guess, i will tell you if you are wrong

camerondoherty · Answer

-6x?

anonymous · Answer

u need to find the two solutions to the equation

anonymous · Answer

lol  no that is way wrong !

camerondoherty · Answer

lol u told me to take a guess xD

camerondoherty · Answer

its 9x right?

anonymous · Answer

$$9x^2-6x+1$$ s the square of $3x-1$ which is another way of saying 
$$(3x-1)^2=9x^2-6x+1$$

anonymous · Answer

(3x-1)(3x-1)

anonymous · Answer

when i said make a guess, i was hoping you would guess one of the possible answers given, not something else!

camerondoherty · Answer

xD

anonymous · Answer

answer is obviously the 3rd one

camerondoherty · Answer

this girl isn't tht bright... lol

anonymous · Answer

all of these problems have to do with recognizing what is a perfect square
i don't actually believe that

anonymous · Answer

it is recognizing that 
$$(a+b)^2=a^2+2ab+b^2$$

anonymous · Answer

in this case you have 
$$9x^2-6x+1$$ which is the same as 
$$(3x-1)^2$$ that is what you are being asked for
