factor w^4-8w^2-9

Solution

factor

w^{4} - 8 w^{2} - 9

Solution

(w^{2} + 1) (w + 3) (w - 3)

Solution steps

w^{4} - 8 w^{2} - 9

Let

u = w^{2}

= u^{2} - 8 u - 9

Factor

u^{2} - 8 u - 9 : (u + 1) (u - 9)

= (u + 1) (u - 9)

Substitute back

u = w^{2}

= (w^{2} + 1) (w^{2} - 9)

Factor

w^{2} - 9 : (w + 3) (w - 3)

= (w^{2} + 1) (w + 3) (w - 3)
