Solve -5x^4=-2x 16

Evaluate

- 5 x^{4} = - 2 x \times 16

Multiply the terms

- 5 x^{4} = - 32 x

Add or subtract both sides

- 5 x^{4} - (- 32 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

- 5 x^{4} + 32 x = 0

Factor the expression

x (- 5 x^{3} + 32) = 0

Separate the equation into 2 possible cases

x = 0 - 5 x^{3} + 32 = 0
