Factor 16x^4-81

16x4−8116x4-81

Rewrite 16x416x4 as (4x2)2(4x2)2.

(4x2)2−81(4x2)2-81

Rewrite 8181 as 9292.

(4x2)2−92(4x2)2-92

Since both terms are perfect squares, factorusing the difference of squares formula, a2−b2=(a+b)(a−b)a2-b2=(a+b)(a-b) where a=4x2a=4x2and b=9b=9.

(4x2+9)(4x2−9)(4x2+9)(4x2-9)

(4x2+9)(2x+3)(2x−3)
