Find the roots

x_{1} = - \frac{6 1215}{3}, x_{2} = \frac{6 1215}{3}

Alternative Form

x_{1} \approx - 1.088867, x_{2} \approx 1.088867

Evaluate

2 x^{5} \times 3 x - 10

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

2 x^{5} \times 3 x - 10 = 0

Multiply the terms

2 x^{5} \times 3 x

Multiply the terms

6 x^{5} \times x

Multiply the terms with the same base by adding their exponents

6 x^{5 + 1}

Add the numbers

6 x^{6}

6 x^{6} - 10 = 0

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

6 x^{6} = 0 + 10

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

6 x^{6} = 10

Divide both sides

\frac{6 x ^{6}}{6} = \frac{10}{6}

Divide the numbers

x^{6} = \frac{10}{6}

Cancel out the common factor 2

x^{6} = \frac{5}{3}

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

x = \pm 6 \frac{5}{3}

x = \pm \frac{6 1215}{3}

Separate the equation into 2 possible cases

x = \frac{6 1215}{3} x = - \frac{6 1215}{3}

Solution

x_{1} = - \frac{6 1215}{3}, x_{2} = \frac{6 1215}{3}

Alternative Form
