x² = 10x
x² - 10x = 0
a = 1
b = -10
x = -b ± √b² - 4ac / 2a
x = -(-10) ± √(-10)² - 4 (1) (0) / 2
x = 10 ± √100/2
x = 10 ± 10/2
x1 = 10 + 10/2 = 10
x2 = 10 - 10/2 = 0
Comprobación
x² - 10x = 0
(10)² - 10(10) = 0
100 - 100 = 0
0 = 0
(0)² - 10(0) = 0
0 - 0 = 0
0 = 0
Espero haberte ayudado. Suerte en los estudios ≧◠◡◠≦.
