Question

suma y resta de polinomios
$p(x) = 6x - 3x - x - 5$
$q(x) = x + 2x + 4$
Calcular
P(x) +Q(x)
Q(x) - P(x) ​

Answer 1

Respuesta:

ok

Explicación paso a paso:

2x - 5 = P

3x + 4 = Q

P(x) + Q(x) = 2x - 5 + 3x + 4 = 5x - 1

Q(x) - P(x) = 3x + 4 - 2x - 5 = x + 1

Answer 2

P(x) + Q(x)

(6x-3x-x-5)+(x+2x+4)=

(6x-4x-5)+(3x+4)=

(2x-5)+(3x+4)= 5x-1

Q(x) - P(x)

(x+2x+4)-(6x-3x-x-5)=

(3x+4)-(6x-4x-5)=

(3x+4)-(2x-5)=

3x+4-2x+5= x+9
