To convert this to vertex form, we must complete the square. This equation is in the form f(x)=ax²+bx+c. To complete the square we take half of b and square it: (-14/2)²=(-7)²=49
This tells us what to add to the function. We must also subtract it from the function, however, in order to preserve equality: p(x) = x²-14x+49+29-49 p(x) = (x-7)²-20
Now that it is in vertex form, we can see that the value of h is 7.
