Question

Solve the quadratic equation by completing the square.

-3x^2+9x=1

Answer 1

This is my answer.

Answer 2

-3x^2+9x=1
3x^2-9x=-1
x^2-3x=-1/3
x^2-3x=-1/3
(x-1/2)^2- 5/2=-1/3
(x-1/2)^2=-1/3+5/2
(x-1/2)^2=13/6
x-1/2= +-square root (13/6)
x= +-square root (13/6)+
x= +-square root (78) /6 + 1/2

I think that is the answer.
