Given the following substances: complete the reaction with the aggregation status of the products; adjustment (balance). Enter the complete ion equation and the net ion.

I already have the equation balanced, but my problem is that I don't understand the "complete ionic and the net ionic"

2K₃PO₄(aq) + 3Sr(NO₃)₂(aq) = Sr₃(PO₄)₂(s) + 6KNO₃(aq)

3 Sr₂+ + 2 PO₄ 3- => Sr₃(PO₄)₂(s)

All other ions will be dissolved before and after.

6 K + + 2 PO₄ 3- + 3 St 2+ + 6 NO₃ - => Sr₃( PO₄)₂(s) + 6 K+ + 6 NO₃ -
