I'm just wondering what the terms actually mean, because the question says "For the quadratic expressions in question 2, decide whether they are positive definite, negative definite or indefinite."

I'm not asking for the answer, just the definitions.

Please help.

Thanks...

Indefinite articles in Spanish are: un - a/an (masculine) una - a/an (feminine) unas - some (feminine) unos - some (masculine) As they are "a/some" they are not specific and indefinite. Definite articles are: la - the (feminine) el - the (mascule) los - those (masculine) las - those (feminine) as they refer to specific objects, they are definite
