The sum of the given polynomial is

[tex]9{x}^{2} - 12{y}^{2} - 11x = 0[/tex]

What is polynomial sum?

The given polynomial expression is:

[tex](8 {x}^{2} - 9 {y}^{2} - 4x) + ( {x}^{2} - 3{y}^{2} - 7x)[/tex]

Remove the brackets

[tex]8 {x}^{2} - 9 {y}^{2} - 4x+ {x}^{2} - 3{y}^{2} - 7x[/tex]

Collect like terms

[tex]8 {x}^{2} + {x}^{2} - 9 {y}^{2} - 3{y}^{2} - 7x - 4x = 0[/tex]

Simplify the expression above

[tex]9{x}^{2} - 12{y}^{2} - 11x = 0[/tex]

Therefore the sum of the given polynomial is:

[tex]9{x}^{2} - 12{y}^{2} - 11x = 0[/tex]
