Solve [x]3 x - a = 0

Evaluate

x \times 3 x - a = 0

Multiply

More Steps

3 x^{2} - a = 0

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

3 x^{2} = 0 + a

Add the terms

3 x^{2} = a

Divide both sides

\frac{3 x ^{2}}{3} = \frac{a}{3}

Divide the numbers

x^{2} = \frac{a}{3}

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

x = \pm \frac{a}{3}

Simplify the expression

More Steps

x = \pm \frac{3 a}{3}

Solution

x = \frac{3 a}{3} x = - \frac{3 a}{3}
