12x^2=x+1
%2812x%5E2-x-1%29=0
Using the quadratic formula for solve for the x-values:
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
.
x+=+%28-%28-1%29+%2B-+sqrt%28%28-1%29%5E2-4%2A12%2A%28-1%29+%29%29%2F%282%2A%2812%29%29+
.
x+=+%28%28%281%29+%2B-+sqrt%281%2B48%29%29%29%2F%2824%29%29%29+%29
.
x+=+%28%28%281%29+%2B-+sqrt%2849%29%29%29%2F%2824%29%29%29+%29
.
x=%281%2B7%2F24%29=%281%2F3%29
or
x=%281-7%2F24%29=%28-1%2F4%29
