The discriminant is the part of the quadratic formula underneath the square root symbol: b²-4ac. The discriminant tells us whether there are two solutions, one solution, or no solutions.

The discriminant is part of the quadratic formula, and because the discriminant is inside a square root sign it cannot be negative, and from the sign of the discriminant we can determine how many roots a …

The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√ …

Analyze quadratic equations in order to determine how many different real number solutions they have.

It's interesting that we can use discriminant to determine the solution of x in quadratic formula. But when if there is no solution, can we argue that the formula is no meaning in some degree.

O discriminante é a parte da fórmula de Bhaskara sob o símbolo da raiz quadrada: b²-4ac. O discriminante nos diz se há duas soluções, uma solução, ou nenhuma solução.

Qu'est-ce que le discriminant ? b 2 4 a c s'appelle le discriminant du trinôme a x 2 + b x + c . C'est l'expression qui est sous le radical dans la formule des racines.

Sal solves -3x^2+10x-3=0 by plugging a=-3, b=10, c=-3 in the quadratic formula. Then he multiplies everything by -1 and solves again. The results are the same!
