= 5x²y + 3xy² + 7x²y + 5xy - 6xy²
= 5x²y + 7x²y + 3xy² - 6xy² + 5xy
= (5 + 7)x²y + (3 - 6)xy² + 5xy
= 12x²y + (3 - 6)xy² + 5xy
= 12x²y - 3xy² + 5xy ✔️
[tex]5 {x}^{2} y + 3 {xy}^{2} + 7 {x}^{2} y + 5xy - 6 {xy}^{2} \\ = (5 {x}^{2} y + 7 {x}^{2} y) +( 3 {xy}^{2} - 6 {xy}^{2} ) + 5xy \\ = 12 {x}^{2} y + ( - 3 {xy}^{2} ) + 5xy \\ = 12 {x}^{2} y - 3 {xy}^{2} + 5xy \\ \\ (d)[/tex]
