Step-by-step explanation:
Let the age of son =x
So, the age of father = x+25
After five years
Age of son =x+5
And age of father =x+30
Acc to question
( Age of father) *(age of son) =600
(x+5) (x=30)=600
x^2+30x +5x+150=600
x^2+35x+150-600=0
x^2+35x-450=0
By middle term spliting
x^2-10x+45x-450=0
x(x-10)+45(x-10)=0
(x+45)(x-10)=0
Taking x+45=0
x=-45
Taking x-10=0
x=10
So age can never be in negative
Therefor x=10
Age of son =x=10
Age of father =x+25=10+25
=35
