Solve 4h^2+5n-636=0

$$4 h ^ { 2 } + 5 n - 636 = 0$$

Solve for n

$$n=\frac{636-4h^{2}}{5}$$

Steps for Solving Linear Equation

Subtract 4h^{2} from both sides. Anything subtracted from zero gives its negation.

$$5n-636=-4h^{2}$$

Add 636 to both sides.

$$5n=-4h^{2}+636$$

The equation is in standard form.

$$5n=636-4h^{2}$$

Divide both sides by 5.

$$\frac{5n}{5}=\frac{636-4h^{2}}{5}$$

Dividing by 5 undoes the multiplication by 5.

$$n=\frac{636-4h^{2}}{5}$$

Solve for h

$$h=\frac{\sqrt{636-5n}}{2}$$

$$h=-\frac{\sqrt{636-5n}}{2}\text{, }n\leq \frac{636}{5}$$
