Question

equação do 2° .
16x ao quadrado+ 4x-2=0

Answer 1

16x² + 4x - 2 = 0

a= 16 ♦ = b² - 4ac
b= 4
c= -2

♦ = (4)² - 4×16(-2)
♦ = 144 → √♦ = 12
√♦= 12

X1,2 = (-b ± √♦ )/2a

X1,2 = ( -4 ± 12 )/2×16

X1 =( -4 + 12)/32 = 8/32
x1 = 0,25

X2 = ( -4 - 12 )/32
X2 = -16/32
x2 = -0,5

Answer 2

16x²+4x-2=0
∆ = b²-4.a.c
16+128
∆ = 144


x'=-b+√∆\2.a
x'=-4+12/32
x'=-8/32
x'=-1/4

x"=-b-√∆\2.a
x"=-16/32
x"=-1/2
