Question

Dados os polinômios P = a + b + c + 1 ; Q = a - b - c + 2 ; R= a + b - c +3 determine: A) P + Q + R B) P + Q - R C) P - Q + R D) P - Q - R

Answer 1

P = a + b + c + 1
Q = a - b - c + 2
R= a + b - c +3

A) P + Q + R

(a + b + c + 1 ) + (a - b - c + 2) + ( a + b - c + 3) =

3a + b - c + 6

B) P + Q - R

(a + b + c + 1 ) + (a - b - c + 2) - ( a + b - c + 3) =

( a - b + c )

C) P - Q + R

(a + b + c + 1 ) - (a - b - c + 2) + ( a + b - c + 3) =

( a + 3b + c + 2)

D) P - Q - R


(a + b + c + 1 ) - ( a - b - c + 2) - ( a + b - c + 3) =

(-3a + b + 3c -4 )
