Solve (x-2x^2 8x 16)=7(x^4)

Evaluate

x - 2 x^{2} \times 8 x \times 16 = 7 x^{4}

Multiply

More Steps

x - 256 x^{3} = 7 x^{4}

Move the expression to the left side

x - 256 x^{3} - 7 x^{4} = 0

Factor the expression

x (1 - 256 x^{2} - 7 x^{3}) = 0

Separate the equation into 2 possible cases

x = 0 1 - 256 x^{2} - 7 x^{3} = 0

Solve the equation

x = 0 x \approx - 36.571322 x \approx - 0.062554 x \approx 0.062447

Solution

x_{1} \approx - 36.571322, x_{2} \approx - 0.062554, x_{3} = 0, x_{4} \approx 0.062447
