Is this statement an Imperative or Subjunctive?

Question

I have a website that I would like to write using the tú form.

I would like to say:

"Keep in mind that Spanish is my second language."

"Tenga en cuenta que español es mi segundo idioma."

I want to use the tú form. The online translator is telling me to use ‘tenga’ which is an usted form, right? Is this statement a Subjunctive or Imperative? So I can conjugate it to the tú form.

Answer 1

Answer 2

ten en cuenta que el español...
