Question

01. Observe as equações do 2° grau na forma reduzida e identifique os valores dos coeficientes a, b e c: x2 + 6x - 11 = 0 a = ________ b = ________ c = ________ -2x2 - 9x + 1 = 0 a = ________ b = ________ c = ________ -x2 + 13x - 4 = 0 a = ________ b = ________ c = ________ x2 + 7x = 0 a = ________ b = ________ c = ________ 2x2 - 32 = 0 a = ________ b = ________ c = ________ 4x2 = 0 a = ________ b = ________ c = ________

Answer 1

Resposta:

x2+6x-11=0

a=1 b=6 c=-11

-2x2 - 9x + 1 = 0

a=-2 b=-9 c=1

x2 + 13x - 4 = 0

a= 1 b=13 c= -4

x2 + 7x = 0

a=1 b=7 c=0

2x2 -32 = 0

a=2 b=0 c=-32

4x2 = 0

a=4 b=0 c=0
