Type your math problem... 15x=15x^5

Question

Solve the equation

x_{1} = - 1, x_{2} = 0, x_{3} = 1

Evaluate

15 x = 15 x^{5}

Add or subtract both sides

15 x - 15 x^{5} = 0

Factor the expression

15 x (1 - x^{4}) = 0

Divide both sides

x (1 - x^{4}) = 0

Separate the equation into 2 possible cases

x = 0 1 - x^{4} = 0

Solve the equation

More Steps

Evaluate

1 - x^{4} = 0

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

- x^{4} = 0 - 1

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

- x^{4} = - 1

Change the signs on both sides of the equation

x^{4} = 1

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

x = \pm 41

Simplify the expression

x = \pm 1

Separate the equation into 2 possible cases

x = 1 x = - 1

x = 0 x = 1 x = - 1

Solution

x_{1} = - 1, x_{2} = 0, x_{3} = 1
