#x=7#

.

#x^2-14x+49=0#

You can solve this either by factoring or using the quadratic formula.

This quadratic is factorable. We need to think of two number such that:

If you multiply them together we will get #49#

And if we add them together algebraically we will get #-14#.

The numbers are #-7# and #-7#. Therefore,

#(x-7)(x-7)=0#

#x-7=0#

#x=7#
