Factor the polynomial and use the factored form to find the real zeros. (Enter your answers as a comma-separated list. Enter all answers including repetitions.)

Question

P(x) = 1/7(2x⁴ + 3x³ − 16x − 24)²

x=

Answer 1

2x⁴- 16x + 3x³ - 24

2x(x³ - 8) + 3(x³ - 8)

(2x + 3)(x³ - 8)

Use difference of cubes to continue and determine zeros (All multiplicity of 2 because of the ^2)
