formula of an arithmetic series - ANS-- Sn = n/2 (2a + (n-1)d) - Sn = n/2 (a + l) where a is the first term and l is the last term what is an arithmetic series - ANS-the sum of the terms of an arithmetic sequence nth term of an arithmetic sequence - ANS-- Un = a + (n-1)d - a = the first term - ...

Factor Theorem - ANS-A polynomial f(x) has a factor (x - a) if and only if f(a) = 0 It has a factor (bx-a) if f(a/b) = 0 Sketching polynomials - ANS-Shape: Reflect in x-axis if there is a negative x Roots: - Crosses x-axis at any root e.g. (x+5) would mean crosses at negative 5 -However, if nega...
