Adding 100 completes the square. { I wonder why you want to complete the square when the expression already factors as x(x-20) }.

1 is the number you are looking for.1 + 12 = 1 + 1 = 2.QED

X2 - 8X = 3halve the linear term (- 8 ), square it and add it to both sidesX2 - 8X + 16 = 3 + 16factor left, gather terms right(X - 4)2 = 19(X - 4)2 - 19 = 0-------------------------(4, - 19)----------------the vertex16 is the number that needed to be added to both sides to complete the square
