+18%5E2+-+27x+%2B+4+
Use the quadratic formula
+x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
+a+=+18+
+b+=+-27+
+c+=+4+
+x+=+%28-%28-27%29+%2B-+sqrt%28+%28-27%29%5E2-4%2A18%2A4+%29%29%2F%282%2A18%29+
+x+=+%28+27+%2B+21%29+%2F+36+
+x+=+48%2F36+
+x+=+8%2F6+
+x+=+4%2F3+
and
+x+=+%28+27+-+21%29+%2F+36+
+x+=+6%2F36+
+x+=+1%2F6+
++x+-+4%2F3+=+0+
+3x+-+4+=+0+
and
+x+-+1%2F6+=+0+
+6x+-+1+=+0+
The factors are:
+%28+3x+-+4+%29%2A%28+6x+-+1+%29+
