factor s^4-16

Solution

factor

s^{4} - 16

Solution

(s^{2} + 4) (s + 2) (s - 2)

Solution steps

s^{4} - 16

Apply exponent rules

= (s^{2})^{2} - 4^{2}

Apply Difference of Two Squares Formula:

x^{2} - y^{2} = (x + y) (x - y)

(s^{2})^{2} - 4^{2} = (s^{2} + 4) (s^{2} - 4)

= (s^{2} + 4) (s^{2} - 4)

Factor

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

= (s^{2} + 4) (s + 2) (s - 2)
