m^{4} - 13 m^{2} + 36 = 0

m = 3, m = - 3, m = 2, m = - 2

Solution steps

m^{4} - 13 m^{2} + 36 = 0

Rewrite the equation with

u = m^{2}

and

u^{2} = m^{4}

u^{2} - 13 u + 36 = 0

Solve

u^{2} - 13 u + 36 = 0 : u = 9, u = 4

u = 9, u = 4

Substitute back

u = m^{2},

solve for

m

Solve

m^{2} = 9 : m = 3, m = - 3

Solve

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

The solutions are

m = 3, m = - 3, m = 2, m = - 2

z^{4} + 3 z^{2} + 2 = 0

x^{4} - 5 x^{2} - 6 = 0

x^{3} - x^{2} - 8 x - 12 = 0

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

72.58 \cdot x^{(14)} = 500
