What is the value of the discriminant b2 4ac for the quadratic equation 0 2x2 3x 8 and what does it mean about the number of real solutions the equation has. Hence the nature of the roots a and v of equation ax 2 bx c 0 depends on the quantity or expression b 2 4ac under the square root sign. In primul rand vei calcula D deltab2-4ac vei obtine o valoareAcea valoare o vei folosi in aflarea celor 2 solutii existente pentru ecuatie si anume x1 si x2.
B 2 - 4ac.
Example 1 Solve 2x2- 7x - 5 0 using the quadratic formula. A x 2 b x c. Heres how the discriminant works. Mozart Violin Concerto No5 in A major KV219 - Bomsori Kim 김봄소리 - Duration.
