To apply the quadratic formula, the right side must be equal to 0.

Now you can apply the quadratic formula

to find the solution for w.

(The quadratic formula is highly unnecessary in this problem, however. You could easily divide all values by 2 to get w²-14w+49=0, which factors into (w-7)²=0, for which 7 is the only solution which puts a factor of the quadratic equal to 0.)
