Answer:
5x3+5x2−55x−15
Step-by-step explanation:
5(x−3)(x2+4x+1)
=(5(x−3))(x2+4x+1)
=(5(x−3))(x2)+(5(x−3))(4x)+(5(x−3))(1)
=5x3−15x2+20x2−60x+5x−15
=5x3+5x2−55x−15
Answer:
5x³ + 5x² - 55x - 15
Step-by-step explanation:
simplify the expression:
5(x − 3)(x² + 4x + 1)
use the distributive property to multiply 5 by x-3
(5x - 15) (x² + 4x + 1)
Use the distributive property to multiply 5x−15 by x²
+4x+1 and combine like terms
5x³ + 5x² - 55x - 15
