\(3x^2 = 48\) is an example of a quadratic equation that can be solved simply. If \((x + 1)(x + 2) = 0\), then \(x + 1 = 0\) or \(x + 2 = 0\), meaning \(x = -1\) or ...

The only real problem is not many quadratic equations have A=1. For example, suppose you throw a ball straight up from 5 meters above the ground with a velocity of 15 m/s. We want to know when the ...

To draw a quadratic graph from an equation: Add up the terms of the quadratic ... graphs to analyse their shooting technique, for example. A rugby or football player could do the same when ...

That year, French mathematician Évariste Galois finally illustrated why this was such a problem—the underlying mathematical ...
