4/(r-4)+(12)/(r+4)=2

\frac{4}{r - 4} + \frac{12}{r + 4} = 2

r = 8, r = 0

Solution steps

\frac{4}{r - 4} + \frac{12}{r + 4} = 2

Multiply by LCM

4 (r + 4) + 12 (r - 4) = 2 (r - 4) (r + 4)

Solve

4 (r + 4) + 12 (r - 4) = 2 (r - 4) (r + 4) : r = 8, r = 0

r = 8, r = 0

Verify Solutions

Find undefined (singularity) points:

r = 4, r = - 4

Combine undefined points with solutions:

r = 8, r = 0

0 = \frac{( x - a ) ^{2}}{x ^{2} + 5}

1 = \frac{70000}{70000 + r}

2 + \frac{1}{x + 2} = (x + 4)^{2}

2 a = \frac{108}{r}

a = \frac{( 1 )}{( 2 ) h ( b + c )}
