First order linear differential equations

To begin with, I have an example problem that asks to find a complete solution for: y'+ 2xy = x The text says to multiply both sides by e^int a(x) dx In this case, that equals e^x^2 It then continues by multiplying. 1) e^x^2 * y' + e^x^2 * 2xy = e^x^2 * x or 2) [e^x^2 * y]' = x * e^x^2 I do not understand h

Discriminants and Quadratic Equations

The standard quadratic equation is given as: ax^2 + bx + c = 0 , where a, b, and c are real numbers and a > 0. The quadratic formula can be used to solve for all solutions of any quadratic equation. If a graph of the quadratic equation crosses the x axis, it has two real number solutions. We use the discriminant of b^2 - 4ac,

Multiples of Quadratic Equations

Two quadratic equations that are multiples of each other are actually the same equation, and that they don't count as being "more than one QE that have the same solution set". However, if you plot the two equations on a graph, will they be different from each other, but have the same x-axis intercepts, which are the answer set?
