Question

URGENTE POR FAVOR


Sejam os polinômios
P1 = x²+ 2x + 10
P = 5x²-8
P3= 2x² - 6x + 5
Dertermine:
a) P1+R2
b) P2 - PB
c) P1+P2+P3
d) P3-P2​

Answer 1

A) P1+P2

x^2+4x+10+5x-12

x^2+4x+5x+10-12

x^2+9x-2

B) P2-P3

(5X-12)-(2X^2-6X+5)

5X-12-2X^2+6X-5

-2X^2+5X+6X-12-5

-2X^2+11X-7

C) P1+P2+P3

X^2+4X+10+5X-12+2X^2-6X+5

X^2+2X^2+4X+5X-6X+10-12+5

3X^2+3X+3

D) P3-P2

2X^2-6X+5-(5X-12)

2X^2-6X+5-5X+12

2X^2-6X-5X+5+12

2X^2-11x+17
