    \(y = -2x^2 + 5x - 4\) vs the form of \(y = ax^2 + bx + c\) Note: sign does matter!

    So that made sense now? Not a hard one, but if you do not know which abc they mean... then it suddenly becomes hard.

    np. I rather people get it than just get an answer. That way you will know it when it is used in later math classes. For example, calculus is about 10% new stuff and 90% doing everything before calculus!
