what is the question here?

anonymous · Answer

4c2 - 12c + 9

anonymous · Answer

that is not a question.. that is an incomplete equation...

anonymous · Answer

well, thats what my paper says

anonymous · Answer

okay.. than I'm going to assume that the complete equation is 4c2-12c+9=0 and the question is find c...

anonymous · Answer

this can be solved by factoring but I can't explain this right here... the answer should be 5.81 or -5.81.. don't just copy though, look for solving quadratic equations on google because there are many ways to solve this question and if you can find one that you get completely you'll be able to solve things like this within a few minutes...

campbell_st · Answer

it can be factorised to

4c^2 -12c + 9 = (2c - 3)^2

which is a perfect square

campbell_st · Answer

if you needed to solve it.... letting the expression = 0

then c = 3/2

@ campbell, i think you're right.. That seems to be the more likely question, I hadn't thought of that :)
