Answer:
[tex]We'd \: better = We \: had \: better. \\ The \: sentence \: "We \: would \\ better \: go" \: is \: not \\ grammatical, \: but \: "We \: had \\ better \: go" \: is, \: so \: you \\ know \: the \: 'd \: is \: "had" \: not \\ "would."" (I \: would \: be \: very \\ unlikley \: to \: actually \: tag \\ that \: statement \: with \: "hadn't \\ we" \: -- it \: sounds \: very \\ unnatural \: to \: me. \: But \: it's \\ grammatically \: correct.)[/tex]
