sqrt(4)=(1/((2+x)))+1

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

x = - 1

Solution steps

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

Simplify

(\frac{1}{( 2 + x )}) : \frac{1}{2 + x}

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

Multiply both sides by

2 + x

2 (2 + x) = x + 3

Expand

2 (2 + x) : 4 + 2 x

4 + 2 x = x + 3

Move

4

to the right side

2 x = x - 1

Move

x

to the left side

x = - 1

Verify Solutions

Find undefined (singularity) points:

x = - 2

Combine undefined points with solutions:

x = - 1

F = \frac{G m _{1} m _{2}}{d ^{2}}

\frac{8}{17} = \frac{5}{7 x}

2 x + 1 = \frac{3}{5 x - 2}

x + \frac{14}{x} = - 9

\frac{1}{x - 1} + \frac{1}{x + 1} = 1
