Finding the Sum (2x2−3xy−2y2)+(5x2−3xy)(2x^2 - 3xy - 2y^2) + (5x^2 - 3xy)

To find the sum (2x2−3xy−2y2)+(5x2−3xy)(2x^2 - 3xy - 2y^2) + (5x^2 - 3xy), rewrite the expression without parentheses as 2x2−3xy−2y2+5x2−3xy2x^2 - 3xy - 2y^2 + 5x^2 - 3xy. Group the like terms together by rearranging the expression: 2x2+5x2−3xy−3xy−2y22x^2 + 5x^2 - 3xy - 3xy - 2y^2. Combine the like terms by adding their coefficients to determine the final sum: 7x2−6xy−2y27x^2 - 6xy - 2y^2.
