How would one change 'ich habe' to be in the past tense?

Ich habe = I have We need to arrive at 'Ich habe gehabt' through Auxiliary + Past Participle The two most common and irregular verbs which need to be memorised are 'haben' and 'sein' HABEN: Ich habe - Du hast - Er/Sie/ Es hat - Wir haben - Ihr habt - Sie haben The conjugation of 'haben' is what we call the Auxiliary and forms the beginning of the past tense, to which the Past Participle can be addedGerman past participles are formed by placing -ge before the verb, taking off the ending (-en) and adding a -t, turning habe into gehabt 'Ich habe' as the Auxiliary + 'gehabt' leads to create the past tense phrase, 'ich habe gehabt' = I have had
