Answer:
distance between the points (2,-3) and (10,p)
is √{(10-2)^2+(p+3)^2} unit
=√{8^2+p^2+6p+9} unit
=√(64+p^2+6p+9) unit
=√(p^2+6p+73)
according to question,
√(p^2+6p+73)=10
=> p^2+6p+73=10^2=100
=> p^2+6p+73-100=0
=> p^2+6p-27=0
=> p^2+9p-3p-27=0
=> p(p+9)-3(p+9)=0
=> (p+9) (p-3)=0
=> p+9=0
=> p= -9
again, p-3=0
=> p=3
so, value of p = 3 , -9
