Factor: 5x4y3 â€“ 80y3
Choose the correct answer.
A) A) 5y3(x2 + 4)(x + 2)(x -2)  B) B) 2y3(x2 + 4)(x + 2)(x -2)  C) C) 3y3(x2 + 4)(x + 2)(x -3)  D) D) 3y3(x2 + 4)(x + 3)(x -2)  E) E) 3y3(x2 + 4)(x + 2)(x -4)
5x4y3â€“ 80y3.   = 5y3(x4 â€“ 16).   = 5y3[(x2)2 - 42].   = 5y3(x2 + 4)(x2 - 4).   = 5y3(x2 + 4)(x2 - 22).   = 5y3(x2 + 4)(x + 2)(x -2).   5y3(x2 + 4)(x + 2)(x -2)nswer: (5y3(x2 + 4)(x + 2)(x -2)) 5y3(x2 + 4)(x + 2)(x -2)
