You shouldn't need a calculator for this. The quadratic equation is written in standard form.
ax^2 + bx + c = 0
You substitute a, b, and c into the discriminant formula and solve as shown in the example in the picture you provided.
(-7)^2 - 4(2)(-8)
49 - 4(-16)
49 - (-64)
49 + 64
113
Best of Luck!
Answer:
uhm ¿Cuál es el divisor de 18 y 30?
Divisores de 12 = 1, 2, 3, 4, 6 y 12. Divisores de 30 = 1, 2, 3, 5, 6, 10, 15 y 30. Divisores de 18 = 1, 2, 3, 6, 9 y 18.
...
1º Descomponemos los números en factores primos. 12 | 2 6 | 2 3 | 3 1 18 | 2 9 | 3 3 | 3 1
2º Los expresamos como potencias. 12 = 22 · 3 18 = 2 · 32
