Multiplying Polynomials

Quick Reminders:

Multiplying Polynomials:

1. Multiply the coefficients.

2. Add the exponents (if they have the same base)

3. Any variables that don't belong? Don't forget them! Keep them in your answer!

1. Multiplica los coeficientes.

2. Suma los exponentes (si tienen la misma base)

3. ¿Hay variables que no pertenecen? ¡No las olvides! ¡Inclúyelas en tu respuesta!
