Question

the product age of suyash before three years and after five years is 153 . find the today age​

Answer 1

Explanation:

let suyash age be x

A/Q

(x-3)(x+5) = 153

x^2 + 5x - 3x - 15 = 153

x^2 + 2x - 168 = 0

x^2 - 14x + 12x - 168 = 0

x (x-14) + 12 ( x - 14)=0

(x+12)(x-14) = 0

x= -12 & x= 14

As - 12 is rejected.

therefote, 14 is the answer.
