Question

The multiplication of 2 consecutive odd natural numbers is 10815. What is the smaller number?​

Answer 1

Step-by-step explanation:

let the two odd consecutive no.be x and x+2

here,x(x+2)=10815

=x²+2x=10815

=x²+2x-10815=0

x²-105x+103x-10813=0

x(x-105)+103(x-105)=0

(x-105)(x+103)=0

x=105 and x=-103

thus here smaller no.is 103
