Question

sum of the ages of a father and his son js 45 .five year ago the product of their ages was 34 the ages of the son and father are respectively​

Answer 1

Answer:

6 , 39

Step-by-step explanation:

let age of son be x

so age of father = 45 - x

(x-5)(45-x-5) = 34

(x-5)(40-x) = 34

40x -200 -x² +5x = 34

0= x² -45x +234

0 = x² -39x -6x +234

0= x(x-39) -6(x-39)

x= 6 , x= 39

since x is age of son ,

x= 6

so ,age of father is 39
