Question

x2+10x-20=0 alguien que me ayude

Answer 1

x² + 10x - 20 = 0

a = 1

b = 10

c = -20

x = -b ± √b² - 4ac / 2a

x = -10 ± √(-10)² - 4 (1) (-20)/2(1)

x = -10 ± √100 - (-80) / 2

x = -10 ± √180/2

x = -10 ± 13.416/2

x1 = -10 + 13.416/2 = 1.708 ≈ 2

x2 = -10 - 13.416/2 = -11.708 ≈ -12

Espero haberte ayudado. Suerte en los estudios ≧◠◡◠≦.
