Answer:

Step-by-step explanation:

Let the present age of father be x and son be y

Age one year ago will be x-1 and y-1

x = y²   -------------(1)

(x-1) = 8(y-1) ---------(2)

Substitute x = y² in (2)

y² - 1 = 8y -8

y²-8y + 7 = 0

y² - 7y -y +7 = 0

y(y-7) - 1(y-7) = 0

(y-1)(y-7) = 0

y=1 or 7

So y = 7 and x=49

Father's age = 49

Son's age = 7.
