Answer 1

Resposta:

a) x² – 3x – 4 = 0

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

b) x + 8x² + 16 = 0

a = 8 , b = 1, c = 16

c) 3x² – 1 = 0

a = 3, b = 0, c = -1

d) – 2x + 1 = 0

a = 0, b = -2, c = 1

e) 5x + 4x² – 1 = 0

a = 4, b = 5, c = -1

f) x² + 15 = x

a = 1, b = -1 , c = 15

g) 9x² – 6x + 1 = 0

a = 9, b = -6, c = 1

h) 2x – 4x² – 1 = 0

a = -4, b = 2, c =-1

i) -x² – x = 3

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

j) x – 1 = - 6x²

a = 6, b = 1, c = -1  

k) x² + 7x + 10 = 0

a = 1, b = 7, c = 10

l) x² – 2x = 0

a = 1, b = -2, c = 0

m) 8x² – 4 = x

a = 8, b = 0, c =-4

n) 8x² + 16 = 0

a = 8, b = 0, c =16

o) 3x – 21 = x²

a = -1, b = 3, c = -21

p) 14x² – 12x + 10 = 0

a = 14, c = -12, c = 10

q) 5 + 4x² – x = 0

a = 4, b = -1, c = 5

r) 2 + 5x² = 0

a = 5, b = 0, c = 2
