Respuesta :

Answer:

1 , -4 , 2 + 5i , 2 - 5i

Step-by-step explanation:

g(x) = (x² + 3x - 4)(x² - 4x + 29)

x² + 3x - 4 = (x-1)(X+4)        x = 1     or x = -4

roots of x² - 4x + 29 = ax² + bx + c

x = (-b ± √b²-4ac) / 2a

x = (4 ± √16 - 4*29) / 2 = (4±√-100) / 2 = (4±10i)/2 = 2 ± 5i

Answer:

B, C, E, F

1, -4, 2+5i, 2-5i
