Step-by-step explanation:

Here,

[tex]1. \: (2x + 2) + (3 - 5x)[/tex]

open brackets,

[tex]2x + 2 + 3 - 5x[/tex]

[tex] = - 3x + 5[/tex]

now,

[tex]2. \: (3x - {4x}^{4} ) + (2x + {5x}^{4} [/tex]

open brackets,

[tex] = 3x - {4x}^{4} + 2x + {5x}^{4} [/tex]

simplifying like terms,

[tex] = {x}^{4} + x[/tex]

Hope it helps...
