Question

descubra quais sao as raízes 2x^2+5x+3=0
e
3x^2+4x+1=0​

Answer 1

descubra quais sao as raízes

2x^2 + 5x + 3 = 0

a = 2. b = 5, c = 3

delta

d = 25 - 24 = 1

as raízes

x1 = (-5 + 1)/4 = -1

x2 = (-5 - 1)/4 = -3/2

3x^2 + 4x + 1 = 0​

a = 3, b = 4, c = 1

delta

d = 16 - 12 = 4

as raízes

x1 = (-4 + 2)/6 = -1/3

x = (-4 - 2)/6 = -1
