Question

Solve the equation by completing the square
-2x^2+x=0

Answer 1

When completing the square
1) make sure x^2 have coeffient of 1, if not divide to get 1
2) Half and square the coefficient of the middle term
3)add the number you get to both side

Answer 2

1)

-2(x^2-1/2x)=0

2)
-2(x^2-1/2x +1/16)=-2/16
-2(x^2-1/2x +1/16)=-1/8
-2 (x-1/4)^2=-1/8
-2(x-1/4)^2+ 1/8
