Question

the product of Rohit age five year ago with his age 9 years later is 15 in year find his present age​

Answer 1

Answer:

rohit presnt age is 6yrs

Answer 2

Answer:

Step-by-step explanation:

Present age = x

Age 5 years ago = x -5

Age 9 years later = x+9

As per question

(x-5)(x+9)=15

x^2 +9x-5x-45 = 15

x^2 +4x -60=0

Solving the quadratic equation we get

x^2+10x -6x -60=0

x(x+10) - 6(x+10) = 0

(x-6)(x+10) = 0

x =6 or x = -10

x = -10 is rejected as age cannot be negative.

Hence the age is 6 years
