Please helpp Solve each polynomial equation by factoring

x^3-3x^2+16x-48=0

x^3-5x^2-3x+15=0

show all work explain it thankss:)

1. x^3-3x^2+16x-48
Factor GCF from each group of two terms: x^2(x - 3) + 16(x - 3)
Factor out (x - 3) :(x^2 + 16)(x - 3)
(x^2 + 16)(x - 3)


2. x^3-5x^2-3x+15
Factor GCF from each group of two terms: x^2(x - 5) - 3(x - 5)
Factor out (x - 5) : (x^2 - 3)(x - 5)
(x^2 - 3)(x - 5)
