Q(x) = x3 - 6x2 + 4
R(x) = 2x4 -2 x - 2
​

Answer 1

Respuesta:

esta es la respuesta

Explicación:

CALCULAR.

1 P(x) + Q (x) - R (X)

= ( X4 - 2X2 - 6X -1 ) +2. ( X3 - 6 X 2 + 4 ) - ( 2X4 - 2X -2)=

= X4 - 2X2 - 6X - 1+2X3 - 12X2 +8 -2X4 +2X+2 =

= X4 - 2X4 + 2X3 -2X2 - 12X2 -6X+2X -1+8+2=

= X4 + 2X3 - 14 X2 - 4X+9

3) Q(x) + R (X)- P(x)

( X3 - 6X2+4 ) + ( 2X4 - 2X -2 ) - ( X4 -2X2 -6X -1 )=

= X3 -6X2+4 +2X4 -2X -2 -X4 +2X2 + 6X +1 =

= 2X4 -X4 +X3 +6X2 +2X2 +2X+6X+4 -2+1 =

= X4 + X3 -4x2 +4X+3 .
