Question

2. Sendo A = x2 + 1 e B= -2x2 + x + 2, determine o valor de: a) A + B b) A - B c) B- O 2x²+x+ 90-38+x+1 0-3x + x + 1 O x-x-3 O 3x²-x-1 0 4x²+2 O-x²+x+3 6x2 - 2x - 2 0-4x2 + 2x​

Answer 1

2. Sendo

A = x² + 1 e

B= -2x² + x + 2

a) A + B

(x²+1)+(-2x²+x+2)

x²-2x²+x+1+2

-x²+x+3

b) A-B

(x²+1)-(-2x²+x+2)

x²+2x²-x-2+1

3x²-x-1

c) B-A

(-2x²+x+2)-(x²+1)

-2x²-x²+x-1+2

-3x²+x+1
