Solve h^2+25A-1800=0

$$h ^ { 2 } + 25 A - 1800 = 0$$

Solve for A

$$A=-\frac{h^{2}}{25}+72$$

Steps for Solving Linear Equation

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

$$25A-1800=-h^{2}$$

Add 1800 to both sides.

$$25A=-h^{2}+1800$$

The equation is in standard form.

$$25A=1800-h^{2}$$

Divide both sides by 25.

$$\frac{25A}{25}=\frac{1800-h^{2}}{25}$$

Dividing by 25 undoes the multiplication by 25.

$$A=\frac{1800-h^{2}}{25}$$

Divide -h^{2}+1800 by 25.

$$A=-\frac{h^{2}}{25}+72$$

Solve for h (complex solution)

$$h=-5\sqrt{72-A}$$

$$h=5\sqrt{72-A}$$

Solve for h

$$h=5\sqrt{72-A}$$

$$h=-5\sqrt{72-A}\text{, }A\leq 72$$
