Solve 3x 7(x 1) = 2(6x^5) - 2x

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

21 x^{2} - 12 x^{5} + 2 x = 0

Factor the expression

x (21 x - 12 x^{4} + 2) = 0

Separate the equation into 2 possible cases

x = 0 21 x - 12 x^{4} + 2 = 0

Solve the equation

x = 0 x \approx - 0.095191 x \approx 1.235277

Solution

x_{1} \approx - 0.095191, x_{2} = 0, x_{3} \approx 1.235277
