2 x^{- 2} = 1

x = 2, x = - 2

Decimal Notation

x = 1.41421 \dots, x = - 1.41421 \dots

Solution steps

2 x^{- 2} = 1

Refine

\frac{2}{x ^{2}} = 1

Multiply both sides by

x^{2}

2 = x^{2}

Solve

2 = x^{2} : x = 2, x = - 2

x = 2, x = - 2

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 2, x = - 2

\frac{31}{3 ( 1 + 2 x )} = \frac{51}{2 ( 2 x - 1 )}

3750 = \frac{1225}{( 0.289 + \frac{0.1}{x} )}

\frac{3}{( x - 4 )} = \frac{2}{( x - 3 )} + \frac{8}{( x ^{2} - 7 x + 12 )}

x, \frac{2}{( x + 2 y )} + \frac{1}{( 2 x - y )} + \frac{5}{9} = 0

\frac{( n + 1 ) !}{( n + 3 ) !} = 600
