Use the quadratic formula where:
a=7
b=12
c=1
.
.
x+=+%28-12+%2B-+sqrt%28+12%5E2-4%2A7%2A1+%29%29%2F%282%2A7%29+[Plug-in the values and solve]
x+=+%28-12+%2B-+sqrt%28+144-28+%29%29%2F%2814%29+ [Combine terms and simplify]
x+=+%28-12+%2B-+sqrt%28+116+%29%29%2F%2814%29+[Factoring 116 = 4*29]
x+=+%28-12+%2B-+2sqrt%2829%29%29%2F%2814%29+
x+=+2%28-6+%2B-+sqrt%2829%29%29%2F%2814%29+ [Factor out "2"]
x+=+%28-6+%2B-+sqrt%2829%29%29%2F%287%29+ [Cancel out]
