(x^2)/(x+80)=40

\frac{x ^{2}}{x + 80} = 40

x = 80, x = - 40

Solution steps

\frac{x ^{2}}{x + 80} = 40

Multiply both sides by

x + 80

x^{2} = 40 (x + 80)

Solve

x^{2} = 40 (x + 80) : x = 80, x = - 40

x = 80, x = - 40

Verify Solutions

Find undefined (singularity) points:

x = - 80

Combine undefined points with solutions:

x = 80, x = - 40

y, x = y + \frac{1}{y}

\frac{30}{x} = 0

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

45 x - 56 = \frac{45}{x}

a = \frac{2 b x}{1 + b ( x - 1 )}
