factor e^4-21e^2-100

Solution

factor

e^{4} - 21 e^{2} - 100

Solution

(e^{2} + 4) (e + 5) (e - 5)

Solution steps

e^{4} - 21 e^{2} - 100

Let

u = e^{2}

= u^{2} - 21 u - 100

Factor

u^{2} - 21 u - 100 : (u + 4) (u - 25)

= (u + 4) (u - 25)

Substitute back

u = e^{2}

= (e^{2} + 4) (e^{2} - 25)

Factor

e^{2} - 25 : (e + 5) (e - 5)

= (e^{2} + 4) (e + 5) (e - 5)
