Question

How would I factor the function f(x) = x^3 + 2x^2 - 25x - 50?

Answer 1

Factor by grouping.

Answer 2

try x +/- the factors of 50
- or yes animal has a good idea

Answer 3

\[f(x) = x^3 + 2x^2 - 25x - 50=x^2(x+2)-25(x+2)=(x^2-25)(x+2)\]\[=(x+5)(x-5)(x+2)\]

Answer 4

Remember the patterns, remember the rules, work carefully. Do math every day.
