if one burger costs (x+3) pesos,how many burgers can you buy for (2x³+6x²+4x+12) pesos?​

Sagot :

Answer:

2 • (x² + 2) • (x + 3)

Step-by-step explanation:

Pull out like factors :

2x³ + 6x² + 4x + 12 =

2 • (x3 + 3x²+ 2x + 6)

:

x³ + 3x² + 2x + 6 is not a perfect cube

Trying to factor by pulling out :

Factoring: x³ + 3x² + 2x + 6

Group 1: 2x + 6

Group 2: x³ + 3x²

Group 1: (x + 3) • (2)

Group 2: (x + 3) • (x²)

-------------------

Add up the two groups :

(x + 3) • (x² + 2)
