Chapter 4 – REVIEW 4.1 - The general polynomial equation : 0 = a n x n + a n-1 x n-1 + . ....... * To solve a polynomial equation means to find the zeros (x-int) of the corresponding function. e.g. (x 2 +2x+3)(x-1) x= (-b±√(b^2-4ac))/2a x = x = 4.2 - Remember the 3 ways to represent an answer: set builder notation, a number line, and interval notation. e.g. -2x + 6 ≤ 0 set builder: x ≥ 3 -2x ≤ -6 number line: 0.
