Factor By grouping.
100 (h + 1)^3 - (h + 1)^5
(h + 1)^3 [100 - (h + 1)^2]
(h + 1)^3 [(10 - (h + 1)(10 + (h + 1)]
Is this correct?
No, it is not.
1) There are missing grouping symbols. 2) It hasn't been factored completely and simplified, such as like terms combined.
100(h + 1)^3 - (h + 1)^5 =
(h + 1)^3*[100 - (h + 1)^2] =
(h + 1)^3* [10 - (h + 1)][10 + (h + 1)] =
(h + 1)^3*[10 - h - 1][10 + h + 1] =
(h + 1)^3*(9 - h)(11 + h) =
(9 - h)(11 + h)(h + 1)^3
