<p>a. (6x<sup>2</sup>y - 5xy + 3xy<sup>2</sup>) + (-9x<sup>2</sup>y + 7xy + 11xy<sup>2</sup>)</p><p> = 6x<sup>2</sup>y - 5xy + 3xy<sup>2</sup> - 9x<sup>2</sup>y + 7xy + 11xy<sup>2</sup></p><p><sup> </sup> =<sup> </sup>-3x<sup>2</sup>y + 2xy + 14xy<sup>2</sup></p><p>b. (-9x<sup>2</sup>y + 7xy + 11xy<sup>2</sup>) - (5x<sup>2</sup> - 9xy - 4y<sup>2</sup>)</p><p> = -9x<sup>2</sup>y + 7xy + 11xy<sup>2</sup> - 5x<sup>2</sup> + 9xy + 4y<sup>2</sup></p><p> = -9x<sup>2</sup>y + 16xy + 11xy<sup>2</sup> - 5x<sup>2</sup> + 4y<sup>2</sup></p>
a. (6x2y - 5xy + 3xy2) + (-9x2y + 7xy + 11xy2)
= 6x2y - 5xy + 3xy2 - 9x2y + 7xy + 11xy2
= -3x2y + 2xy + 14xy2
b. (-9x2y + 7xy + 11xy2) - (5x2 - 9xy - 4y2)
= -9x2y + 7xy + 11xy2 - 5x2 + 9xy + 4y2
= -9x2y + 16xy + 11xy2 - 5x2 + 4y2

<p>a. (6x²y-5xy+3xy²)+(-9x²y+7xy+11xy²)</p><p>= 6x²y-5xy+3xy²-9x²y+7xy+11xy²</p><p>= (6-9)x²y + (-5+7)xy + (3+11)xy²</p><p>= -3x²y + 2xy + 14xy².</p><p> </p><p>b. (-9x²y+7xy+11xy²)-(5x²-9xy-4y²)</p><p>= -9x²y+7xy+11xy²-5x²+9xy+4y²</p><p>= -9x²y+(7+9)xy+11xy²-5x²+4y²</p><p>= -9x²y + 16xy + 11xy² - 5x²+4y².</p>
a. (6x²y-5xy+3xy²)+(-9x²y+7xy+11xy²)
= 6x²y-5xy+3xy²-9x²y+7xy+11xy²
= (6-9)x²y + (-5+7)xy + (3+11)xy²
= -3x²y + 2xy + 14xy².
b. (-9x²y+7xy+11xy²)-(5x²-9xy-4y²)
= -9x²y+7xy+11xy²-5x²+9xy+4y²
= -9x²y+(7+9)xy+11xy²-5x²+4y²
= -9x²y + 16xy + 11xy² - 5x²+4y².
