Factoring Polynomials Completely

Question 12 • [INMT3] Integrated Math 3 Sem 1 (26-27)

Factor out the common factor.

Answer
A
2x4 + 5x3 – 8x –20
B
(x3 + 4)(–2x – 5)
C
(x3 – 4)(2x + 5)
D
(x3 + 4)(2x + 5)

Explanation

Group the terms: (2x⁴ + 5x³) + (−8x − 20). Factoring each group gives x³(2x + 5) − 4(2x + 5), so the common factor is (2x + 5). The result is (x³ − 4)(2x + 5), choice C.
