3 x^{4} = 12

x = 2, x = - 2, x = 2 i, x = - 2 i

Solution steps

3 x^{4} = 12

Divide both sides by

3

x^{4} = 4

Rewrite the equation with

u = x^{2}

and

u^{2} = x^{4}

u^{2} = 4

Solve

u^{2} = 4 : u = 4, u = - 4

u = 4, u = - 4

Substitute back

u = x^{2},

solve for

x

Solve

x^{2} = 4 : x = 2, x = - 2

Solve

x^{2} = - 4 : x = 2 i, x = - 2 i

The solutions are

x = 2, x = - 2, x = 2 i, x = - 2 i

x^{2} - 4 x = - 11

c^{2} - 1 c

1 2^{2} + b^{2} = 2 0^{2}

x + 5 > 7
