Question

a)Adicionar (x2 – 3x – 1) + ( –3x2 + 8x – 6)
B)Subtrair (5x2 – 9x – 8) – (–3x2 + 10x – 6)
C)Se multiplicarmos (3x – 1) por (5x2 + 2)

Answer 1

Resposta:

(x²-3x-1)+(-3x²+8x-6)

x²-3x-1-3x²+8x-6

x²-3x²-3x+8x-1-6

-2x²+5x-7

(5x²-9x-8)-(-3x²+10x-6)

5x²-9x-8+3x²-10x+6

5x²+3x²-9x-10x-9+6

8x²-19x-3

(3x-1)(5x²+2)

15x³+6x-5x²-2

15x³-5x²+6x-2
