Question 1174204
<br>
{{{w(w+30) = 10591}}}
{{{w^2+30w-10591 = 0}}}<br>
You can try to factor this, by finding two numbers whose product is 10591 and whose difference is 30.  But that is what the original problem asks you to do -- so the use of formal algebra doesn't get you any closer to the solution.<br>
Alternatively, you can always solve a quadratic equation using the quadratic formula.  But with this equation, the calculations are ugly.<br>
By far the easiest way to solve the problem is to find the prime factorization of 10591 and use it to find the solution.<br>
There are many prime factorization calculators on the internet; they will show you<br>
10591 = 7*17*89<br>
It takes only a moment to combine the first two prime factors to find the solution to the problem:<br>
10591 = 119*89<br>
