Look at the National 4 factorising section before continuing. When a question asks you to 'solve' a quadratic equation, this means that you are to find the roots of the quadratic. In other words ...

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

Write down the nature of the turning point and the equation of the axis of symmetry. For the parabola \(y=(x+6)(x-4)\) determine the coordinates and nature of its turning pont and the equation of ...
