Answer:

PA = PB

 {pa}^{2}  =  {pb}^{2}  \\  {(2 + 2)}^{2  }  +  {(2 - k)}^{2}   =  {(2 + 2k)}^{2}  +  {(2 + 3)}^{2}  \\  {4}^{2}  + 4 - 4k +  {k}^{2}  = 4 + 8k + 4 {k}^{2}  +  {5}^{2}  \\ 16 + 4 - 4k +  {k}^{2}  = 4 + 8k +  {4k}^{2}  + 25 \\  {3k}^{2 }  + 12k  + 9 = 0 \\    {k}^{2}  + 4k + 3 = 0 \\ (k + 1)(k + 3) = 0 \\ k =  - 1 \: or \: k =  - 3 \\  =  =  =  =  =  =  =  =  =  =  =  \\

using the value of k find AP
