Answer 2

Answer:

12 and 45

Step-by-step explanation:

let the person be x.

let the age of son be y.

x+y=57.____(1)

x+y=540____(2)

finding the value of x from____(1)

x=57-y

now putting this value in.____(2)

57-y×y=540

57y-y power 2 =540

y power 2 57 y + 540=0

y power 2 -(45y+12y)+540 =0

y power 2 -45y+12y +540=0

y(y-45)-12(y-45)=0

(y-12)(y-45)= 0.
