Question

The product of two positive integer is 176. One number is 5 more than the other. Find the smaller number

Answer 1

Answer :11.

let's "n" be the smaller .Then n* (n+5)=176

My first reaction to this problem was to factor 176 is my head .thats 176=16* and 16 is 5 more than 11

So that's the solution !......Now let's solve it's using the buret force approach.

n(n+5)=176

n^2+5n -176=0. = use it
