factor m^4+3m^2-4

Solution

factor

m^{4} + 3 m^{2} - 4

Solution

(m + 1) (m - 1) (m^{2} + 4)

Solution steps

m^{4} + 3 m^{2} - 4

Let

u = m^{2}

= u^{2} + 3 u - 4

Factor

u^{2} + 3 u - 4 : (u - 1) (u + 4)

= (u - 1) (u + 4)

Substitute back

u = m^{2}

= (m^{2} - 1) (m^{2} + 4)

Factor

m^{2} - 1 : (m + 1) (m - 1)

= (m + 1) (m - 1) (m^{2} + 4)
