Solve x^2 7x^2 (-2x) 3x^2 = 1

Evaluate

x^{2} \times 7 x^{2} (- 2 x) \times 3 x^{2} = 1

Multiply

More Steps

- 42 x^{7} = 1

Change the signs on both sides of the equation

42 x^{7} = - 1

Divide both sides

\frac{42 x ^{7}}{42} = \frac{- 1}{42}

Divide the numbers

x^{7} = \frac{- 1}{42}

Use \frac{- a}{b} = \frac{a}{- b} = - \frac{a}{b} to rewrite the fraction

x^{7} = - \frac{1}{42}

Take the 7 -th root on both sides of the equation

7 x^{7} = 7 - \frac{1}{42}

Calculate

x = 7 - \frac{1}{42}

Solution
