Solve 25x^2+36y-900=0

$$25 { x }^{ 2 } +36y-900=0$$

Solve for y

$$y=-\frac{25x^{2}}{36}+25$$

Steps for Solving Linear Equation

Subtract 25x^{2} from both sides. Anything subtracted from zero gives its negation.

$$36y-900=-25x^{2}$$

Add 900 to both sides.

$$36y=-25x^{2}+900$$

The equation is in standard form.

$$36y=900-25x^{2}$$

Divide both sides by 36.

$$\frac{36y}{36}=\frac{900-25x^{2}}{36}$$

Dividing by 36 undoes the multiplication by 36.

$$y=\frac{900-25x^{2}}{36}$$

Divide 900-25x^{2} by 36.

$$y=-\frac{25x^{2}}{36}+25$$

Solve for x (complex solution)

$$x=-\frac{6\sqrt{25-y}}{5}$$

$$x=\frac{6\sqrt{25-y}}{5}$$

Solve for x

$$x=\frac{6\sqrt{25-y}}{5}$$

$$x=-\frac{6\sqrt{25-y}}{5}\text{, }y\leq 25$$
