x^{4} - 1 = 25 x^{2}

x = \frac{3.14009 E 15}{1.0 E 15}, x = - \frac{3.14009 E 15}{1.0 E 15}

Solution steps

x^{4} - 1 = 25 x^{2}

Square both sides:

x^{8} - 2 x^{4} + 1 = 25 x^{2}

x^{8} - 2 x^{4} + 1 = 25 x^{2}

Solve

x^{8} - 2 x^{4} + 1 = 25 x^{2} : x = \frac{4.98411 E 15}{1.25 E 17}, x = - \frac{4.98411 E 15}{1.25 E 17}, x = \frac{3.14009 E 15}{1.0 E 15}, x = - \frac{3.14009 E 15}{1.0 E 15}

x = \frac{4.98411 E 15}{1.25 E 17}, x = - \frac{4.98411 E 15}{1.25 E 17}, x = \frac{3.14009 E 15}{1.0 E 15}, x = - \frac{3.14009 E 15}{1.0 E 15}

Verify Solutions:

x = \frac{4.98411 E 15}{1.25 E 17}

False

, x = - \frac{4.98411 E 15}{1.25 E 17}

False

, x = \frac{3.14009 E 15}{1.0 E 15}

True

, x = - \frac{3.14009 E 15}{1.0 E 15}

True

The solutions are

x = \frac{3.14009 E 15}{1.0 E 15}, x = - \frac{3.14009 E 15}{1.0 E 15}

x (6 - 2 x^{0.5}) + 2 = 0

1 = 1 b^{2.5}

x + x + x - 1 = 6

x - 4 = 5

2 x^{- 1} + x^{\frac{- 1}{2}} = 6
