At first glance, it might be tempting to say this is a linear function, because we see linear terms (3x and –6x); however, these are multiplied together, so it's actually a quadratic.
We need to expand the function (hint: use FOIL) to identify the terms.
The x^2-term, or quadratic term, is
. The x-term, or linear term, is
. The number term, or constant term, is –20.

Answer:
Chiara has 2 penny coins and 24 nickel coins
Step-by-step explanation:
Let
p ----> the number of penny coins
n ---> the number of nickel coins
Remember that
Chiara has 26 coins that equal 34 cents
so
isolate the variable x
----> equation A
34 cents=$0.34
Multiply by 100 both sides
isolate the variable x
-----> equation B
Create a table to guess
assume different values of n and determine the value of p in equation A and equation B
The solution is when the value of p in the equation A must be equal to the value of p in equation B
1) For n=1
equation A
equation B
2) For n=2
equation A
equation B
therefore
The solution is (2,24)
