Best ResponseYou've already chosen the best response.0oh wait. nvm. this is a bad example for perfect squares. use the quadratic formula

Best ResponseYou've already chosen the best response.0Whats the quadratic formula?

Best ResponseYou've already chosen the best response.0A quadratic equation is of the form \[ax^2+bx+c=0\] By method of completing the square , we write this as \[a(xh)^2+constant\]

Best ResponseYou've already chosen the best response.0So its dw:1359606358086:dw

Best ResponseYou've already chosen the best response.0no. because u do not have a c then last part of the term in the square root should be o. it should just be rad 15^2.

Best ResponseYou've already chosen the best response.0nope. u have to simplify. u should come out with 2 answers for x.

Best ResponseYou've already chosen the best response.0oh whoops. my bad. it should be over 6

Best ResponseYou've already chosen the best response.0Why is it over 6 then?

Best ResponseYou've already chosen the best response.0because ur a is 3. for the standard equation it is ax^2+bx+c

mopsy510

Best ResponseYou've already chosen the best response.0Ohh so you have to multiply it by 2?

Best ResponseYou've already chosen the best response.0Can you help me with 16y^2+25=25

blahblah_who_cares

Best ResponseYou've already chosen the best response.0are u sure u arent saying 16y^2+25y=25?

blahblah_who_cares

Best ResponseYou've already chosen the best response.0well that makes it simple. what do you think u have to do?

mopsy510
 2 years ago
Best ResponseYou've already chosen the best response.0I think i have to subtract 25 from each side so it becomes 16y^2=0

blahblah_who_cares

Best ResponseYou've already chosen the best response.0and what is the only possible answer for y?

blahblah_who_cares
 2 years ago
Best ResponseYou've already chosen the best response.0no. there is only 1 possible answer in the world for the term y. So what do you think y equals.

blahblah_who_cares

Best ResponseYou've already chosen the best response.0so what u are telling me is that 16*196^2=0?

mopsy510
 2 years ago
Best ResponseYou've already chosen the best response.0Isn't it suppose to have 2 answers?

blahblah_who_cares

Best ResponseYou've already chosen the best response.0for this equation no. for the previous one yes.

mopsy510

Best ResponseYou've already chosen the best response.0Ok. How would i complete the square for the equation y^23y?

blahblah_who_cares
 2 years ago
Best ResponseYou've already chosen the best response.0u would not want to complete the square for it unless u have to. do u have to?

mopsy510

Best ResponseYou've already chosen the best response.0It just says "complete the square"

mopsy510

Best ResponseYou've already chosen the best response.0It doesn't say solve but the next equations say to solve

blahblah_who_cares

Best ResponseYou've already chosen the best response.0ok here is the way u would do it. u would first make the equation equal to zero. Then u get half of b and square it. and the square to both sides. in this case it would be 1.5^2. then you would get (x+1.5)^2=1.5^2. Square root. x+1.5=1.5 Something like that. my math may be wrong because im starting to feel not that great. Hope that helped.
