Question

x²-6x-72=0 formula general​

Answer 1

Respuesta:

Explicación paso a paso:

6x² - 6x - 72 = 0

x = -(-6) ± √ (-6)² - 4 × 6 × (-72) / 2 × 6

x = 6 ± √ 36 + 1728 / 12

x = 6 ± √ 1764 / 12

x = 6 ± 42 / 12

x = 6 + 42/ 12 = 48 / 12 = 4

6 - 42 / 12 = - 36 / 12 = -3

[menor] x = -3

[mayor] x = 4
