Mathematicians once turned up their noses at imaginary numbers. But complex analysis actually simplifies math and physics.

The quadratic formula for a quadratic equation in the form of \(ax^2 + bx + c = 0\) is \(x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\). The first solution is \(x = \frac ...

A quadratic equation is drawn as a curve on a set of ... x = 1 and x = 2. You have now found all of the values you need to draw your graph! Image caption, Step 5 – Plot a graph using the values ...
