Question

Resolva,em R,a equação 6x²-7x+2=0

Answer 1

Olá Karingen

6x² - 7x + 2 = 0

delta
d² = 49 - 48 = 1
d = 1

x1 = (7 + 1)/12 = 8/12 = 2/3
x2 = (7 - 1)/12 = 6/12 = 1/2 

.

Answer 2

6x²-7x+2=0
Δ=b²-4.a.c
Δ=(-7)²-4.6.2
Δ=49-48
Δ=1
x=-b+-√Δ/2.a
x=-(-7)+-√1/2.6
x=+7+-1/12
x1=8/12=2/3
x2=6/12=1/2
