Question

Consideramos los polinomios P = x − 5x + 4, Q = 3x + 2x + 6. Calcula:

a) P + Q

b) P − Q

c) Q − P


porfavor

Answer 1

Respuesta:

P= x - 5x + 4 = 4 - 4x

Q= 3x + 2x + 6 = 5x + 6

a) P + Q = 4 - 4x + 5x + 6 = x + 10

b) P - Q = 4 - 4x - (5x + 6) = -9x - 2

c) Q - P = -(P - Q) = -(-9x - 2) = 9x + 2
