Hi,

x%5E2%2F3%2B7x%5E1%2F3%2B12=0

Multiplying thru with 3 to clear the denominators

x%5E2+%2B7x%5E1+%2B+36+=+0

using quadratic formula o solve

x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+ 

there are no real solutions

x+=+%28-7+%2B-+sqrt%28+-95+%29%29%2F%282%29+ 

Solutions involving imaginary numbers would be as follows:

x+=+%28-7+%2B-+i%2Asqrt%28+95+%29%29%2F%282%29+
