Question

dados os polinomios P= x+3 Q=x-y+5 R= 2x+3y-2 determine:

a)P+Q+R B)P+Q-R C)P-Q+R



D)P-Q-R E)P.Q.R F) P.P

Answer 1

P=x+3
Q=x-y+5
R=2x+3y-2

•A===P+Q+R=
(x+3)+(x-y+5)+(2x+3y-2)=
X+3+x-y+5+2x+3y-2=
4x+2y+6

B===P+Q-R
(x+3)+(x-y+5)-(2x+3y-2)
X+3+x-y+5-2x-3y+2
10-4y

C===p-q+r
(X+3)-(x-y+5)+(2x+3y-2)
X+3-x+y-5+2x+3y-2
2x+4y-4


D===p-q-e (X+3)-(x-y+5)-(2x+3y-2) X+3-x+y-5-2x-2y+2 -2x-y. . . . . F===p.p (X+3).(x+3) ;;; x2+3x+3x+(3)2 ;;; x2+6x+9 ; Espero ter ajudado❤
