Americans pronounce favorable as FAY-vuh-ruh-buhl (/ˈfeɪvərəbəl/). The L in "favorable" is a dark L — the back of the tongue rises toward the soft palate, adding a small "uh" quality before the L. This is called the Dark L vs Light L, a small move that separates 'classroom' from 'native'. It comes out as FAY·vuh·ruh·buhl. Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "The deal includes favorable terms for future collaborations".

Start with your jaw slightly open and the front of your tongue forward and slightly up. Glide upward, your jaw closes a little more and your tongue arches higher toward the roof of the mouth.
The textbook way isn't wrong — it's just not how anyone actually says it.
The L in "favorable" is a dark L — the back of the tongue rises toward the soft palate, adding a small "uh" quality before the L. Dark L adds a small schwa-like "uh" before the L. The back of the tongue lifts toward the soft palate.
In "favorable", the short unstressed vowel before "r" disappears — the schwa is absorbed and the "r" becomes the syllable nucleus on its own. Schwa is absorbed — consonant becomes the syllable nucleus.
Stress falls on the first syllable, not the others. Stretch FAY — keep everything else short and quick.
Don't pronounce the first syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
