$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Here's the solution :

$\qquad \sf \dashrightarrow \:(2 {x}^{2} + 5x - 7) + (3 - 4 {x}^{2} + 6x)$

$\qquad \sf \dashrightarrow \: 2{x}^{2} + 5x - 7 + 3 - 4 {x}^{2} + 6x$

$\qquad \sf \dashrightarrow \:2 {x}^{2} - 4 {x}^{2} + 5x + 6x - 7 + 3$

$\qquad \sf \dashrightarrow \: - 2 {x}^{2} + 11x - 4$
