Question

Resolva equaçao 2 grau

Answer 1

a=8

b=-14

c=3

delta = (-14)^2 - 4*8*3 = 196-96 = 100

x= -b+- 10/2*a

x1 = 14 + 10/16

x1= 24/16 = 3/2

x2= 14-10/16

x2 = 4/16 = 1/4

========================

a = 12

b = 17

c = 6

delta = 17^2 -4*12*6

delta = 289 - 288

delta = 1

x = -17 +- 1/24

x1 = -17+1/24 = - 2/3

x2 = -17 -1/24 = - 3/4
