Question

Simplify the expression

14 - 3 x^{4}

Evaluate

14 - 3 x^{2} \times x^{2}

Solution

More Steps

Evaluate

3 x^{2} \times x^{2}

Multiply the terms with the same base by adding their exponents

3 x^{2 + 2}

Add the numbers

3 x^{4}

14 - 3 x^{4}

Show Solution

x_{1} = - \frac{4 378}{3}, x_{2} = \frac{4 378}{3}

Alternative Form

x_{1} \approx - 1.469778, x_{2} \approx 1.469778

Evaluate

14 - 3 x^{2} \times x^{2}

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

14 - 3 x^{2} \times x^{2} = 0

Multiply

More Steps

Multiply the terms

3 x^{2} \times x^{2}

Multiply the terms with the same base by adding their exponents

3 x^{2 + 2}

Add the numbers

3 x^{4}

14 - 3 x^{4} = 0

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

- 3 x^{4} = 0 - 14

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

- 3 x^{4} = - 14

Change the signs on both sides of the equation

3 x^{4} = 14

Divide both sides

\frac{3 x ^{4}}{3} = \frac{14}{3}

Divide the numbers

x^{4} = \frac{14}{3}

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

x = \pm 4 \frac{14}{3}

\frac{4 378}{3}

x = \pm \frac{4 378}{3}

Separate the equation into 2 possible cases

x = \frac{4 378}{3} x = - \frac{4 378}{3}

Solution

x_{1} = - \frac{4 378}{3}, x_{2} = \frac{4 378}{3}

Alternative Form

x_{1} \approx - 1.469778, x_{2} \approx 1.469778
