Factor b 12 + 8.
(b4 - 2)(b16 + 2b4 + 4)
(b4 + 2)(b8 - 2b4 + 4)
(b4 - 2)(b8 + 2b4 + 4)
(b4 + 2)(b16 - 2b4 + 4) **Weegy:** The factor of b^12 + 8 is: (b^4+ 2)(b^8- 2b^4+ 4) **User:** a 3 - 1 **Weegy:** 4[(6 - 1) + 3(5 - 2)] = 4[(5) + 3(3)]; = 4(5 + 9); = 4 * 14; = 56 (More)

a^3 - 1

= (a - 1) {a(a + 1) + 1 }

= (a - 1) (a^2 + a + 1)

= (a - 1) {a(a + 1) + 1 }

= (a - 1) (a^2 + a + 1)

Factor this expression completely, and, then, place the factors in the proper location on the grid. Place the binomial factor first.
a^3 - 1

a^3 - 1

= (a - 1) a(a + 1) + 1

= (a - 1) (a^2 + a + 1)

= (a - 1) a(a + 1) + 1

= (a - 1) (a^2 + a + 1)
