30 x^{4} - 30 x^{2} = 0

x = 1, x = - 1, x = 0

Solution steps

30 x^{4} - 30 x^{2} = 0

Rewrite the equation with

u = x^{2}

and

u^{2} = x^{4}

30 u^{2} - 30 u = 0

Solve

30 u^{2} - 30 u = 0 : u = 1, u = 0

u = 1, u = 0

Substitute back

u = x^{2},

solve for

x

Solve

x^{2} = 1 : x = 1, x = - 1

Solve

x^{2} = 0 : x = 0

The solutions are

x = 1, x = - 1, x = 0

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

3 x^{4} - 7 x - 3 x^{2} + 5 x + 2 = 0

x^{4} - 2 x^{3} - 6 x^{2} = 0

1.576 = (1 + x)^{3}

420 = 130 x^{3} + 30
