Discriminant equations are an important class of Diophantine equations with close ... Over his career he has obtained several significant and pioneering results, among others on unit equations and ...

The discriminant for a quadratic equation \(a ... and since the question already gave us the quadratic in its factorised form, we will use this to solve to find values for \(x\).

{4}=0\) \(25+5k=0\) Rearrange to make \(k\) the subject. The discriminant is \({b^2} - 4ac\), which comes from the quadratic formula and we can use this to find the nature of the roots. Roots can ...

Canonical discriminant analysis is a dimension-reduction technique related to principal component analysis and canonical correlation. Given a classification variable and several interval variables, ...
