Linear discriminant analysis (LDA) is a versatile statistical method for reducing redundant and noisy information from an original sample to its essential features. Particularly, LDA is a supervised ...

If \(kx^{2}+5x-\frac{5}{4}=0\) has equal roots, then \(b^2-4ac=0\). \(a=k\), \(b=5\) and \(c= - \frac{5}{4}\). \(b^2-4ac=0\) \(5^2 -4\times k \times - \frac{5}{4}=0 ...
