Solve x^2 -6x^6 - ScanMath

Question

Factor the expression

x^{2} (1 - 6 x^{4})

Evaluate

x^{2} - 6 x^{6}

Rewrite the expression

x^{2} - x^{2} \times 6 x^{4}

Solution

x^{2} (1 - 6 x^{4})

Show Solution

x_{1} = - \frac{4 216}{6}, x_{2} = 0, x_{3} = \frac{4 216}{6}

Alternative Form

x_{1} \approx - 0.638943, x_{2} = 0, x_{3} \approx 0.638943

Evaluate

x^{2} - 6 x^{6}

To find the roots of the expression,set the expression equal to 0

x^{2} - 6 x^{6} = 0

Factor the expression

x^{2} (1 - 6 x^{4}) = 0

Separate the equation into 2 possible cases

x^{2} = 0 1 - 6 x^{4} = 0

The only way a power can be 0 is when the base equals 0

x = 0 1 - 6 x^{4} = 0

Solve the equation

More Steps

Evaluate

1 - 6 x^{4} = 0

Move the constant to the right-hand side and change its sign

- 6 x^{4} = 0 - 1

Removing 0 doesn't change the value,so remove it from the expression

- 6 x^{4} = - 1

Change the signs on both sides of the equation

6 x^{4} = 1

Divide both sides

\frac{6 x ^{4}}{6} = \frac{1}{6}

Divide the numbers

x^{4} = \frac{1}{6}

Take the root of both sides of the equation and remember to use both positive and negative roots

x = \pm 4 \frac{1}{6}

More Steps

Evaluate

4 \frac{1}{6}

To take a root of a fraction,take the root of the numerator and denominator separately

\frac{4 1}{4 6}

Simplify the radical expression

\frac{1}{4 6}

Multiply by the Conjugate

\frac{4 6 ^{3}}{4 6 \times 4 6 ^{3}}

Simplify

\frac{4 216}{4 6 \times 4 6 ^{3}}

Multiply the numbers

\frac{4 216}{6}

x = \pm \frac{4 216}{6}

Separate the equation into 2 possible cases

x = \frac{4 216}{6} x = - \frac{4 216}{6}

x = 0 x = \frac{4 216}{6} x = - \frac{4 216}{6}

Solution

x_{1} = - \frac{4 216}{6}, x_{2} = 0, x_{3} = \frac{4 216}{6}

Alternative Form

x_{1} \approx - 0.638943, x_{2} = 0, x_{3} \approx 0.638943
