Work Step by Step
When we set two polynomials equal to each other we obtain a $\textbf{polynomial}$ equation. The equation is in standard form if one side is $\textbf{zero}$ and the polynomial on the other side is in standard form, which means in $\textbf{decreasing}$ powers of the variable. The degree of the equation is the $\textbf{highest}$ degree of any term in the equation.
