factor 3m^4-8m^2-16

Solution

factor

3 m^{4} - 8 m^{2} - 16

Solution

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

Solution steps

3 m^{4} - 8 m^{2} - 16

Let

u = m^{2}

= 3 u^{2} - 8 u - 16

Factor

3 u^{2} - 8 u - 16 : (3 u + 4) (u - 4)

= (3 u + 4) (u - 4)

Substitute back

u = m^{2}

= (3 m^{2} + 4) (m^{2} - 4)

Factor

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

= (3 m^{2} + 4) (m + 2) (m - 2)
