Answer:

a. 7x^2-15=32x

Step-by-step explanation:

a standard form quadratic equation is written as ax^2+bx+c=0

7x^2-15=32x can be rewritten into 7x^2-32x-15=0 by subtracting 32x on both sides.

options b and c don't work  because they include another variable, y

option d is a linear equation, not a quadratic
