How do I use the "Completing the Square" method in solving for c?

Question

as in ax^2+by+c

Answer 1

hi...

is it y as the variable or constants or suppose it is = x?

Answer 2

Your question is not clear,how do you solve for c since it is

not an equation nor an inequality ? Please check it.

Answer 3

write it as (sqrt(a)x)^2 + 2(b/2)y+c

so second term is 2AB first is A^2 and last is B^2

A=sqrt(a)x

B=sqrt(c)

AB=(b/2)y=sqrt(a)x X sqrt(c)

so c is [(b/2)y/(sqrt(a)x)]^2
