\(3x^2 = 48\) 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 ...

In particular, they show that any quantum computation can be encoded into an instance of solving linear equations, even with the restrictions required for their quantum solver to be efficient.

When integrating simple expressions, the constant of integration, the \(+ c\) term, may remain an unknown. The value of \(c\) can be worked out when additional information is given in the question, ...

The mathematicians are concentrating on solving the equations in spite ... "The solutions of the simple equations can then be combined—simply added up, so to speak—to arrive at a solution ...
