James is five years old now and Emma is four years older.(adsbygoogle = window.adsbygoogle || []).push({});

Form a relevant equation and use it to find out how many years it will take until James' and Emma's age in years, multiplied together will make 725 years.

I'm needing help to form the equation. Anyway, from what I've done so far, I know that James will be 25 and Emma will be 29 when their age multiplied together will make 725.

Anyway what I've tried so far:

X(X+4) = 725

25(25+4) = 725

I think the proper equation would be something like this:

X² + 4 = 725

But then wouldn't the next part be something like:

X² = 725 - 4

If so, I have no idea how I'm suppose to get 25 from:

(X = blank)( X = blank) = 721
