0.00 + -26w + w2 = 0 + -148.75
-26w + w2 = 0 + -148.75

Combine like terms: 0 + -148.75 = -148.75
-26w + w2 = -148.75

The w term is -26w.  Take half its coefficient (-13).
Square it (169) and add it to both sides.

Add '169' to each side of the equation.
-26w + 169 + w2 = -148.75 + 169

Reorder the terms:
169 + -26w + w2 = -148.75 + 169

Combine like terms: -148.75 + 169 = 20.25
169 + -26w + w2 = 20.25
