Solution

factor

c^{4} - 81

Solution

(c^{2} + 9) (c + 3) (c - 3)

Solution steps

c^{4} - 81

Apply exponent rules

= (c^{2})^{2} - 9^{2}

Apply Difference of Two Squares Formula:

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

(c^{2})^{2} - 9^{2} = (c^{2} + 9) (c^{2} - 9)

= (c^{2} + 9) (c^{2} - 9)

Factor

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

= (c^{2} + 9) (c + 3) (c - 3)
