Question

2) Considerando ax + bx + c = 0, com a # 0, determine os coeficientes das
equações.
a) -3x2 + 6x = 0
b) 3x2 - 12 = 0
c) 25 - 10x + x2 = 0
d) 4x2 = 0​

Answer 1

Oie, Td Bom?!

a)

$- 3x {}^{2} + 6x = 0$

$ax {}^{2} + bx + c = 0$

• Coeficientes:

$a = - 3 \: ,\: b = 6 \: , \: c = 0$

b)

$3x {}^{2} - 1 2=0$

$ax {}^{2} + bx + c = 0$

• Coeficientes:

$a = 3 \: ,\: b = 0 \: , \: c = - 12$

c)

$25 - 10x + x {}^{2} = 0$

$x {}^{2} - 10x + 25 = 0$

$ax {}^{2} + bx + c = 0$

• Coeficientes:

$a = 1 \: , \: b = - 10 \: ,\: c = 25$

d)

$4x {}^{2} = 0$

$ax {}^{2} + bx + c = 0$

• Coeficientes:

$a = 4 \: , \: b = 0 \: , \: c = 0$
