This also tells the number of roots and whether or not the roots are real or imaginary. What is the discriminant formula? The discriminant formula is d=b^2-4ac given the equation of the quadratic is f(x)=ax^2+bx+c. The formula derives from the quadratic formula. Moreover, the ...
This information is useful as it serves as a double check when we solve quadratic equations by any of the four techniques. The four techniques are factoring, completing the square, using square roots, and using the quadratic formula.Share with friends FacebookTwitterWhatsAppPrevious Spherical ...
A polynomial discriminant is the product of the squares of the differences of the polynomial roots r_i. The discriminant of a polynomial is defined only up to constant factor, and several slightly different normalizations can be used. For a polynomial p

In terms of the roots, the discriminant is equal to Technically, one can derive the formula for the quadratic equation without knowing anything about the discriminant. Then, if you plug derived expressions for the roots into the definition above, you will end up with the . In terms of the...
The discriminant of a quadratic equation equals b2 - 4a, the radicand in theQuadratic Formula. It allows you to determine the nature of the roots of a quad-ratic equation without actually solving for them.1. Ifb^2-4ac0 , there are two real, unequal roots.When b2 - 4ac is a perfect...
Let U be a Haar distributed matrix in 𝕌(n) or 𝕆(n). We show that after centering the two-parameter process [Formula: see text] converges in distribution to the bivariate tied-down Brownian bridge. TRUNCATIONS OF HAAR UNITARY MATRICES, TRACES AND BIVARIATE BROWNIAN BRIDGE ...
A recent conjecture of Daqing Wan hypothesizes, for certain $p$-adic Lie towers of curves over $\mathbb{F}_p$, a stable (polynomial) growth formula for the genus. Here we prove the analogous result in characteristic zero, namely: the $p$-adic valuation of the discriminant of the ...
These are generalizations of Shintani’s asymptotic formulae of the mean values of class numbers of binary cubic forms over Z. 1. Introduction Let k be a number ?eld and O the ring of integers of k. Let r1 and r2 be the number of real and complex places of k. We denote by ?k ,...
