Question

complete the square
y^2+36=13y

Answer 1

y^2+36=13y
y^2- 13y + 36=0
y^2- 13y = - 36
-13/2

y^2 -13y + (-13/2)^2= -36 +(-13/2)^2
can you finish it

Answer 2

y^2+(-13/2)^2=49+(-13/2)^2
is tht right so far?

Answer 3

13y can NOT be added or subtracted from 36

Answer 4

ohh haha i totally didn't think about tht :D

Answer 5

i will do it using letters
y^2+b=ay
y^2-ay=-b

take 1/2 *a then square it (a/2)^2 lets make c= (a/2)^2

y^2 - ay + c =-b + c
(y-a)^2 = -b + c

try it
