Question

2)Agora escreva esses polinômios a seguir, na forma reduzida:
a) ( 2x2 – 8x + 3) + ( 3x2 + 5x - 1)
d) ( 5x2 - 2x + 7) - (3x2 + 7x - 1)​

Answer 1

Resposta:

a) ( 2x2 – 8x + 3) + ( 3x2 + 5x - 1)

$2x^{2}$ - 8x + 3 + $3x^{2}$ + 5x - 1

$5x^{2}$ - 3 + 2

d) ( 5x2 - 2x + 7) - (3x2 + 7x - 1)​

$5x^{2}$ - 2x + 7 - $3x^{2}$ - 7x + 1

$2x^{2}$ - 9x + 8
