Ca(OH)_2 + H_3PO_4 -> Ca_3(PO_4)_2 + H_2O (unbalanced)

Explanation:

Writing calcium hydroxide + phosphoric acid yield calcium phosphate + water in chemical equation would be,
Ca(OH)_2 + H_3PO_4 -> Ca_3(PO_4)_2 + H_2O

but it still needs to be balanced. To balance this, you just have to ensure that there is an equal amount of elements in both the reactant and product side.

Balancing this would result to,

3Ca(OH)_2 + 2H_3PO_4 -> Ca_3(PO_4)_2 + 6H_2O
