Simplify 2h+3h^2-4g^4+5f^2+11g^4-4h+f^2

$2 h + 3 h^{2} - 4 g^{4} + 5 f^{2} + 11 g^{4} - 4 h + f^{2}$

Subtract $4 h$ from $2 h$ .

$3 h^{2} - 4 g^{4} + 5 f^{2} + 11 g^{4} - 2 h + f^{2}$

Add $- 4 g^{4}$ and $11 g^{4}$ .

$3 h^{2} + 7 g^{4} + 5 f^{2} - 2 h + f^{2}$

Add $5 f^{2}$ and $f^{2}$ .

$3 h^{2} + 7 g^{4} + 6 f^{2} - 2 h$

Move $3 h^{2}$ .

$7 g^{4} + 6 f^{2} + 3 h^{2} - 2 h$
