Question

what is the difference between linear and quadratic polynomials?

Answer 1

heya.

Linear polynomial is a polynomial of degree 1.
eg xy+y

Quadratic polynomial is a polynomial of degree 2.
eg ab+ b^2

Answer 2

In a linear equation (such as y=5x+2, for example), x is raised to the power of 1. In a quadratic equation (such as y=x^2+6), x is raised to the power of 2.Also, the graph of a linear equation is a straight line (normally at an angle, although not necessarily always), while the graph of a quadratic equation is a parabola.
