Question

2x²-10x=0 ( Preciso do Delta )

Answer 1

Δ = b²-4.a.c
Δ= (-10)²-4.2.0
Δ=100

Answer 2

2x² - 10x = 0


delta = b² - 4.a.c

a = 2
b = -10
c = 0


delta = (-10)² - 4.2.0
delta = 100 - 0
delta = 100


x = -b ± √delta/2.a

x = -(-10) ± √100/2.2

x = 10 ± 10/4

x = 10 - 10/4 = 0/4 = 0

x = 10 + 10/4 = 20/4 = 5


s={ 0, 5 }
