Question

Dados polinômios P= a+b+c; Q =a+-b-c; R= a-b-c A) P+Q+R? b) p+q-r? c) p-q+r? d)p-q-r ?

Answer 1

 P= a+b+c; Q =a+-b-c; R= a-b-c

A) P+Q+R = a+b+c+a-b-c+a-b-c = 3a - b - c 

b) p+q-r = a+b+c+a-b-c-a+b+c = a + b + c

c) p-q+r = a+b+c-a+b+c+a-b-c = a + b + c 

d)p-q-r = a+b+c-a+b+c-a+b+c = - a + 3b + 3c
