Question

Resolva as adições algébricas entre os polinômios:

a) (– 3x² +4x – 6) + (5x² + x + 2)

b) (y² – 4 + 8yx) – (3 + yx – y²) + (–3yx + 2y² + 2)

​

Answer 1

a) (-3x² + 4x - 6) + (5x² + x + 2)

-3x² + 4x - 6 + 5x² + x + 2

2x² + 5x - 4

b) (y² – 4 + 8yx) – (3 + yx – y²) + (–3yx + 2y² + 2)

y² - 4 + 8xy - 3 - xy + y² - 3xy + 2y² + 2

4y² - 5 + 4xy
