The correct option is B 6
Let the son's age be x.
Since the sum of their ages is 44. Let the mother's age be 44−x.
Using the given relation, we have the following equation.
44−x=x2+2
⇒x2+x−42=0
⇒x2+7x−6x−42=0
⇒x(x+7)−6(x+7)=0
⇒(x−6)(x+7)=0
⇒x=6,x=−7
Since age cannot be negative, x=6.
That is, the son is 6 years old.
