factor 9m^4-40m^2+16

Solution

factor

9 m^{4} - 40 m^{2} + 16

Solution

(3 m + 2) (3 m - 2) (m + 2) (m - 2)

Solution steps

9 m^{4} - 40 m^{2} + 16

Let

u = m^{2}

= 9 u^{2} - 40 u + 16

Factor

9 u^{2} - 40 u + 16 : (9 u - 4) (u - 4)

= (9 u - 4) (u - 4)

Substitute back

u = m^{2}

= (9 m^{2} - 4) (m^{2} - 4)

Factor

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

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

Factor

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

= (3 m + 2) (3 m - 2) (m + 2) (m - 2)
