As a graph cuts the axis when the y coordinate is zero, then we substitute \(y = 0\) into the quadratic equation and use algebra to solve. We need to factorise the trinomial. When factorised this ...

Both \(b\) and/or \(c\) can be equal to zero. In this section, solving equations where \(a >1\) will be considered. To solve a quadratic equation Rearrange the equation so that the Right Hand Side ...

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

At some point during your time at school, you will have found yourself sitting in math class and wondering why you're being taught the quadratic formula. Unless you've found yourself a career in a ...

Their work extends Newton’s method to efficiently handle the broadest class of functions yet, pushing the centuries-old technique to new heights. “Newton’s method has 1,000 ...

you will get solutions to a whole new set of quadratic equations. In fact, a whole amazing and useful world of mathematics comes into view: the world of complex analysis. For one, trigonometry ...
