1. ## good definitions

hey i have to write a math paper and i was lookin for some good definitions for the following terms:

quadratic polynomial
quadratic equation
solution

2. Quadratic polynomial - Wikipedia, the free encyclopedia

Quadratic equation - Wikipedia, the free encyclopedia

an explanation of the solution to a quadratic equation is explained in the quadratic equation link.

quadratic polynomial
this is an expression of the form

$ax^2 + bx + c$

quadratic equation
this is an equation of the form

$ax^2 + bx + c = 0$

solution
these are the values that solve an equation.

for instance, this would be the set of x-values that solve the quadratic equation above

a,b, and c are real constants
