Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{4 {x}^{3} + 6 {y}^{2} }}}}}$

Step-by-step explanation:

$\sf{5 {y }^{2} + 5 - 4 - 4 {y}^{2} + 5 {y}^{2} - 4 {x}^{3} - 1}$

Collect like terms

⇒ $\sf{ 4 {x}^{3} + 5 {y}^{2} - 4 {y}^{2} + 5 {y}^{2} + 5 - 4 - 1}$

⇒ $\sf{4 {x}^{3} + {y}^{2} + 5 {y}^{2} + 5 - 4 - 1}$

⇒ $\sf{4 {x}^{3} + 6 {y}^{2} + 5 - 4 - 1}$

Calculate

⇒ $\sf{4 {x}^{3} + 6 {y}^{2} + 1 - 1}$

⇒ $\sf{4 {x}^{3} + 6 {y}^{2} }$

Hope I helped!

Best regards! :D
