how old is my child

Question

how old is my child

anonymous · Answer

my child’s age, increased by 3, gives a perfect square, and when decreased by 3
the age is the square root of that perfect square. How old is the child?

hero · Answer

x = age of child

x + 3 = y^2
x - 3 = y

x + 3 = (x - 3)^2
x + 3 = x^2 - 6x + 9
x^2 - 7x + 6 = 0
(x - 6)(x - 1) = 0

x = 6

He knows the age of  his child. He's just giving it to us as a challenge so that we can figure it out. @Luis_Rivera
