\frac{1}{1 - x ^{2}} = 1.55

x = \frac{561}{31}, x = - \frac{561}{31}

Decimal Notation

x = 0.76404 \dots, x = - 0.76404 \dots

Solution steps

\frac{1}{1 - x ^{2}} = 1.55

Multiply both sides by

1 - x^{2}

\frac{1}{1 - x ^{2}} 1 - x^{2} = 1.55 1 - x^{2}

Simplify

1 = 1.55 1 - x^{2}

Switch sides

1.55 1 - x^{2} = 1

Multiply both sides by

100

155 1 - x^{2} = 100

Divide both sides by

155

1 - x^{2} = \frac{20}{31}

Square both sides:

1 - x^{2} = \frac{400}{961}

1 - x^{2} = \frac{400}{961}

Solve

1 - x^{2} = \frac{400}{961} : x = \frac{561}{31}, x = - \frac{561}{31}

x = \frac{561}{31}, x = - \frac{561}{31}

Verify Solutions:

x = \frac{561}{31}

True

, x = - \frac{561}{31}

True

The solutions are

x = \frac{561}{31}, x = - \frac{561}{31}

4 (1 + x)^{2} = 6

x^{\frac{1}{3}} = 3

x, x + 4 x y + 2 y = a

x, 3 x - 11 x - 4 = 0
