Quadratic equations and complex numbers
... If P(x) is a polynomial whose coefficients (and constant) are integers, C is the set of all factors, positive and negative, of the constant term of P(x), and D is the set of all factors of the leading coefficient of P(x), then all rational solutions to P(x) = 0 must be of the form p/q, where p is a ...

Math 142–Rodriguez Lehmann–3.1 system of linear equations
... 2. By inspection, state the solution set. (What do the lines do: intersect, parallel, or same line?) 3. Check the solution in both original equations (when there is one solution). Examples: Find the solution set of the system by graphing the equations by hand. If the system is inconsistent or depend ...
