You're supposed to do this:
\[\frac{3}{z4} \times 1 + \frac{6}{z + 3} \times 1\]
\[\left(\frac{3}{z4} \times \frac{z+3}{z+3}\right) + \left(\frac{6}{z+3} \times \frac{z4}{z4}\right)\]

The denominators need work. See if you can understand this:
\[(z  4)(z + 3) = z(z + 3)  4(z + 3) = z^2 + 3z  4z  12 = z^2  z  12\]
