Answer 1

Respuesta:

${x}^{4} - 12x - 64 = 0$

$x \: \: \: \: \: \: \: \: - 16 \\ x \: \: \: \: \: \: \: \: \: \: + 4$

x=16 y x= -4

${x}^{3} - {x}^{2} - 10x - 8$

$(x - 2)(x + 2)(x - 1)=0$

x=2 ; x = -2 ; x=1

$- {x}^{3} + 5 {x}^{2} - 2x + 10 = 0$

$( x - 5)( - 1)( {x}^{2} + 2) = 0$

$(x - 5)( {x}^{2} + 2) = 0$

x= 5 ; x = ✓2 i ; x = -✓2 i

${x}^{4} - 5 {x}^{2} - 36 = 0$

$( x - 3)(x + 3)( {x}^{2} + 4) = 0$

x = 3 ; x = -3 ; x= - 2 i x= 2i

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

$(6x + 2)( - {x}^{2} - 1) = 0$

$(- 1)(2)(3x + 2)( {x}^{2} + 1) = 0$

$(3x + 2)( {x}^{2} + 1) = 0$

x= -2/3 ; x= i ; x = -i
