Question

The product of two consecutive natural number is 110.Find the number

Answer 1

Let 1 no be x

2 no will be x+1

atq

x (x+1)=110

x^2+x=110

x^2+x-110=0

quadratic eq

p=-110,s=1

nos are 11 and -10
.
x^2+11x-10x-110=0(splitting middle term)

x (x+11)-10 (x+11)=0

(x+11)(x-10)=0

x=-11 or x=10

as they are natural nos

so x cant be negative

nos are 10 and x+1 =11
