Answer:

A = 3

B = -5

C = 2

Step-by-step explanation:

The way to format a quadratic equation is: $ax^2 + bx + c$ , so the first step to solving this is to format it in the right way, where the $x^2$ comes first, the $x$ second, and the number alone.

After formatting, your equation should look like this: $3x^2 - 5x + 2$

From here, you can see the the a is 3, the b is -5, and the c is 2
