use perfect squares.
 one year ago

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

Whats the quadratic formula?
 one year ago

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

do not complete the square on this problem. the b is not divisible by 2.

mopsy510Best ResponseYou've already chosen the best response.0
So if i dont complete the suare what do i do?
 one year ago

blahblah_who_caresBest ResponseYou've already chosen the best response.0
the quadratic equation. which i have written.

blahblah_who_caresBest ResponseYou've already chosen the best response.0
that is the formula^^^
 one year ago

mopsy510Best ResponseYou've already chosen the best response.0
So its dw:1359606358086:dw

blahblah_who_caresBest ResponseYou've already chosen the best response.0
no. 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.

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

blahblah_who_caresBest ResponseYou've already chosen the best response.0
oh whoops. my bad. it should be over 6
 one year ago

mopsy510Best ResponseYou've already chosen the best response.0
Why is it over 6 then?
 one year ago

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

mopsy510Best ResponseYou've already chosen the best response.0
Ohh so you have to multiply it by 2?

Can you help me with 16y^2+25=25
 one year ago

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

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

mopsy510Best ResponseYou've already chosen the best response.0
I think i have to subtract 25 from each side so it becomes 16y^2=0
 one year ago

blahblah_who_caresBest ResponseYou've already chosen the best response.0
and what is the only possible answer for y?
 one year ago

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

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

mopsy510Best ResponseYou've already chosen the best response.0
Isn't it suppose to have 2 answers?
 one year ago

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

mopsy510Best ResponseYou've already chosen the best response.0
Ok. How would i complete the square for the equation y^23y?
 one year ago

blahblah_who_caresBest ResponseYou've already chosen the best response.0
u would not want to complete the square for it unless u have to. do u have to?
 one year ago

mopsy510Best ResponseYou've already chosen the best response.0
It just says "complete the square"
 one year ago

mopsy510Best ResponseYou've already chosen the best response.0
It doesn't say solve but the next equations say to solve
 one year ago

blahblah_who_caresBest ResponseYou've already chosen the best response.0
ok 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.
