Solve 7-(2x^4)=-(x-4)

Evaluate

7 - 2 x^{4} = - (x - 4)

Calculate

7 - 2 x^{4} = - x + 4

Move the expression to the left side

7 - 2 x^{4} - (- x + 4) = 0

Subtract the terms

More Steps

3 - 2 x^{4} + x = 0

Factor the expression

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

Separate the equation into 2 possible cases

- 1 - x = 0 2 x^{3} - 2 x^{2} + 2 x - 3 = 0

Solve the equation

More Steps

x = - 1 2 x^{3} - 2 x^{2} + 2 x - 3 = 0

Solve the equation

x = - 1 x \approx 1.204095

Solution

x_{1} = - 1, x_{2} \approx 1.204095
