         OPERACIONES CON POLINOMIOS

$\purple{\texttt{A - B + C}}$

x² + 3xy + 6y² - (-5x³ + 5xy + 6x² - y²) + (6x³ + 4xy - 2x² + y²)

x² + 3xy + 6y² + 5x³ - 5xy - 6x² + y² + (6x³ + 4xy - 2x² + y²)

-5x² - 2xy + 7y² + 5x³ + 6x³ + 4xy - 2x² + y²

11 x³ + 8y² -7x² + 2xy

RPTA: 11 x³ + 8y² -7x² + 2xy

$\purple{\texttt{A + B + C}}$

x² + 3xy + 6y² + 5x³ + 5xy + 6x² - y² + 6x³ + 4xy - 2x² + y²

5x² + 3xy + 6y² + 5x³ + 5xy - y² + 6x³ + 4xy + y²

5x² + 3xy + 6y² + 5x³ + 5xy + 6x³ + 4xy

5x² + 12xy + 6y² + 5x³ + 6x³

5x² + 12xy + 6y² + 11x³

RPTA: 5x² + 12xy + 6y² + 11x³

$\purple{\texttt{(A - B) + (A + C)}}$

[(x² + 3xy + 6y²) - (-5x³ + 5xy + 6x² - y²) + (x² + 3xy + 6y² + 6x³ + 4xy - 2x²+ y²)]

[x² + 3xy + 6y² + 5x³ - 5xy - 6x² + y² + x² + 3xy + 6y² + 6x³ + 4xy - 2x²+ y²]

11x³ + 14y² + 5xy - 6x²

RPTA: 11x³ + 14y² + 5xy - 6x²

$\purple{\texttt{A - (B + A + C)}}$

A - B - A + C

C - B

6x³ + 4xy - 2x² + y² - (-5x³ + 5xy + 6x² - y²)

6x³ + 4xy - 2x² + y² + 5x³ - 5xy - 6x² + y²

11x³ - xy - 8x² + 2y²

RPTA: 11x³ - xy - 8x² + 2y²
