Question

Nas equações abaixo determine os valores dos coeficientes a,b e c

a) x² - 5x + 6 = 0
b) - 2+x² -2x = 0
c) -x+ 2x² + 10 = 0
d) -3x +1 -3x² = 0
e) 2x² = 0
f) -2x² -14 = 0
g) -3x +x² = 0
h) 3 - x² -5x = 0

Answer 1

_________________________

ax² + bx + c = 0

_________________________

A) x² - 5x + 6 = 0

a = 1,b = -5,c = 6

_________________________

B) -2 + x² - 2x = 0

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

_________________________

C) -x + 2x² + 10 = 0

a = 2,b = -1,c = 10

_________________________

D) -3x + 1 - 3x² = 0

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

_________________________

E) 2x² = 0

a = 2,b = 0,c = 0

_________________________

F) -2x² - 14 = 0

a = -2,b = 0,c = -14

_________________________

G) -3x + x² = 0

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

_________________________

H) 3 - x² - 5x = 0

a = 1,b = -5,c = 3
