I just know the greatest common factor is 2ab
But i don’t know if it is foil method but I still don’t know how to put it in that format
X - the amount of money collected by Aiden
y - the amount of money collected by Jacob
Aiden and Jacob collected money in the ratio of 3.5 : 6.8.

Jacob collected $115.50 more than Aiden.

The total amount of money they collected is
$360.50.
The function
is a quadratic function due to the highest exponent being 2.
Given functions are:




<h3>What is a quadratic function?</h3>
A function of the form
with
is called a quadratic function means the highest exponent of polynomial should be 2.
Let us check one by one.

Highest exponent =2
The function is also of form
so u(x) is a quadratic function.
The functions v(x), y(x), and z(x) are having highest exponents as 3,5, and 3 respectively so they are not quadratic functions.
Hence, the function
is a quadratic function due to the highest exponent being 2.
