Type your math problem... -14x=3x^3

x

Question

Solve the equation

x = 0

Evaluate

- 14 x = 3 x^{3}

Add or subtract both sides

- 14 x - 3 x^{3} = 0

Factor the expression

- x (14 + 3 x^{2}) = 0

Divide both sides

x (14 + 3 x^{2}) = 0

Separate the equation into 2 possible cases

x = 0 14 + 3 x^{2} = 0

Solve the equation

More Steps

Evaluate

14 + 3 x^{2} = 0

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

3 x^{2} = 0 - 14

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

3 x^{2} = - 14

Since the left-hand side is always positive or 0,and the right-hand side is always negative,the statement is false for any value of x

x \in / R

x = 0 x \in / R

Solution

x = 0
