What is the defining feature of a quadratic equation?

A

The highest power of the variable is 3 (usually in the form ax3+bx2+cx+d=0ax^3+bx^2+cx+d=0ax3+bx2+cx+d=0).

B

The highest power of the variable is 1 (usually in the form ax+b=0ax+b=0ax+b=0).

C

The equation contains exactly 2 terms involving the variable (usually in the form ax2+bx=0ax^2+bx=0ax2+bx=0).

D

The highest power of the variable is 2 (usually in the form ax2+bx+c=0ax^2+bx+c=0ax2+bx+c=0).
