This is the process I would use:
Maddy's = 2x 2x+x=15
Meg's = x 3x=15

I believe 3.7 is your answer
Answer:
The smallest zero is 
Step-by-step explanation:
The given function is
To find the zeros of this function, we equate it to zero.
Dividing through by 4 gives
We split the middle term to get;
Factor
Factor further to get;


The zeros are

The smallest zero is

First, we are going to write it like this:

Then, we are going to do something like factoring, but it's not factoring. An example would be:

If we apply it, we would be left with:

We cancel the common factors, and we are left with:

That's our final answer.
Let me know if you need any more help!
