In elementary algebra, a trinomial is a polynomial consisting of three terms or monomials.

Trinomial expressions

  1. 3x+5y+8z with x,y,z variables
  2. 3t+9s^{2}+3y^{3} with t,s,y variables
  3. 3ts+9t+5s with t,s variables
  4. Ax^{a}y^{b}z^{c}+Bt+Cs with x,y,z,t,s variables, a,b,c nonnegative integers and A,B,C any constants.
  5. Px^{a}+Qx^{b}+Rx^{c} where x is variable and constants a,b,c are nonnegative integers and P,Q,R any constants.

Trinomial equation

A trinomial equation is a polynomial equation involving three terms. An example is the equation x=q+x^{m} studied by Johann Heinrich Lambert in the 18th century.[1]
