Type your math problem... 3(2x^3) = -5x

x

Question

Solve the equation

x = 0

Evaluate

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

Multiply the numbers

6 x^{3} = - 5 x

Add or subtract both sides

6 x^{3} - (- 5 x) = 0

If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses

6 x^{3} + 5 x = 0

Factor the expression

x (6 x^{2} + 5) = 0

Separate the equation into 2 possible cases

x = 0 6 x^{2} + 5 = 0

Solve the equation

More Steps

Evaluate

6 x^{2} + 5 = 0

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

6 x^{2} = 0 - 5

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

6 x^{2} = - 5

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
