This is the equation written in standard form, I'm not sure if that's what you wanted.
If you would like to complete the factorization, you can do this using the following step:
9g^2 + 30g + 25 = (3g + 5) * (3g + 5) = (3g + 5)^2

Answer:
She catered for 40 people.
Step-by-step explanation:
According to the information given, you can write an equation that indicates that 30 people multiply for its cost that is $10 plus the number of people after 30 for its cost that is $9 is equal to $390. According to this, the equation is:
10(30)+9x= 390, where
x= number of people after 30
Then, you can solve for x:
300+9x= 390
9x=390-300
9x= 90
x=90/9
x=10
The answer is that she catered for 40 people, 30 people at a cost of $10 and 10 people for a cost of $9.
