Question

find two consecutive odd numbers whose product is 99

Answer 1

The numbers are 9 and 11 .....

Their product is 9 × 11 = 99

Answer 2

let odd numbers are in form x,x+2
x(x+2)=99
x^2+2x=99
x^2+2x-99=0
x^2+11x-9x-99=0
x(x+11)-9(x+11)=0
x=9 or -11
negative value is not possible
so the numbers are 9,11
