\(a^3+4a^2-29a+24\)

\(=a^3-a^2+5a^2-5-24a+24\)

\(=a^2\left(a-1\right)+5a\left(a-1\right)-24\left(a-1\right)\)

\(=\left(a-1\right)\left(a^2+5a-24\right)\)

\(=\left(a-1\right)\left(a^2-3a+8a-24\right)\)

\(=\left(a-1\right)\left(a\left(a-3\right)+8\left(a-3\right)\right)\)

\(=\left(a-1\right)\left(a-3\right)\left(a-8\right)\)
