Question

product of minal age three years ago and two years hence is 126. find her present age

Answer 1

Answer:

present age is 12 years

Step-by-step explanation:

3 years ago age was x-3

2 years later age will be x+2

(x-3)(x+2)=126 given

x^2-x-6-126=0

x^2-x-132=0 middle term split x^2-12x+11x-132

(x-12)(x+11) x=12,-11

since age can't be in negative so present age will be 12 years. hope it helps you thanks
