Question

indique os coeficiente do 2° grau A)15x²-5x-2=0 B)4x²+56=0 C)x²-2x=0 D)-3x²-12x+ 25=0 E)5x²-3x-2=0 F)3x²+14=0 G)x²-6x=0 H)x²-5x+2=0​

Answer 1

A) 15x² - 5x - 2 = 0

a = 15

b = - 5

c = - 2

B) 4x² + 56 = 0

a = 4

b = 0

c = 56

C) x² - 2x = 0

a = 1

b = - 2

c = 0

D) -3x² - 12x + 25 = 0

a = - 3

b = - 12

c = 25

E) 5x² - 3x - 2 = 0

a = 5

b = - 3

c = - 2

F) 3x² + 14 = 0

a = 3

b = 0

c = 14

G) x² - 6x = 0

a = 1

b = - 6

c = 0

H) x² - 5x + 2 = 0

a = 1

b = - 5

c = 2
