Question

Identifique os coeficientes das equações abaixo:
a)3x² + 4x + 1 = 0
b)x² - x - 1 = 0
c)9x² - 5x = 0
d)14x² - 6 = 0
e)x² + 9 = 0
f)8x² - 9x = 0
g)17x² - 5x = 0
h)14x² = 0

Answer 1

Explicação passo-a-passo:

a) 3x² + 4x + 1 = 0

-> a = 3, b = 4, c = 1

b) x² - x - 1 = 0

-> a = 1, b = -1, c = -1

c) 9x² - 5x = 0

-> a = 9, b = -5, c = 0

d) 14x² - 6 = 0

-> a = 14, b = 0, c = -6

e) x² + 9 = 0

-> a = 1, b = 0, c = 9

f) 8x² - 9x = 0

-> a = 8, b = -9, c = 0

g) 17x² - 5x = 0

-> a = 17, b = -5, c = 0

h) 14x² = 0

-> a = 14, b = 0, c = 0
