\frac{x ^{2}}{4} = \frac{8}{x + 4}

x \approx 2.26079 \dots

Solution steps

\frac{x ^{2}}{4} = \frac{8}{x + 4}

Cross multiply

x^{2} (x + 4) = 32

Solve

x^{2} (x + 4) = 32 : x \approx 2.26079 \dots

x \approx 2.26079 \dots

Verify Solutions

Find undefined (singularity) points:

x = - 4

Combine undefined points with solutions:

x \approx 2.26079 \dots

x, \frac{1}{a x} + 7 = 25

r, n = \frac{P V}{r T}

8 x - \frac{2}{5 x} + 7 = 3

\frac{x + 2}{14} = \frac{14}{x + 2}

\frac{1}{2 x + 4} = 7 \frac{1}{2}
