Solving quadratic equations start with getting one side of the equation equal to zero. So we'll subtract 7 from each side:

Next we would either factor the non-zero side or use the Quadratic Formula. Normally I prefer factoring but this equation does not factor. So we must use the Quadratic Formula, . Using this on our equation we get:

Simplifying we get:
