Question

If difference in the ages of nidhi and nisha is 2 years and product of their ages is 728.Construct a quadratic equation to find their ages

Answer 1

Step-by-step explanation:

let

Age of nidhi = x

Age of nisha = y

difference of their age =2

then

x-y=2

y=x-2 equation(1)

product of their age =728

x×y=728

x(x-2) =728

x^2-2x=728

x^2-2x-728=0
