Question

Sabstract 5x^2-6y^2+8y-5 from 7x^2-5xy+10y^2+5x-4y

Answer 1

$7 {x}^{2} - 5xy + 10 {y}^{2} + 5x - 4y - ( \\ 5 {x}^{2} - 6 {y}^{2} + 8y - 5)$

$7 {x}^{2} - 5xy + 10 {y}^{2} + 5x - 4y - \\ 5 {x}^{2} + 6 {y}^{2} - 8y + 5$

$7 {x}^{2} - 5 {x}^{2} + 10 {y}^{2} + 6 {y}^{2} + 5x - \\ 4y - 8y - 5xy + 5$

$2 {x}^{2} + 16 {y}^{2} + 5x - 12y - 5xy + 5$
