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

Answer:
-1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5x=6x+1
Step 2: Subtract 6x from both sides.
5x−6x=6x+1−6x
−x=1
Step 3: Divide both sides by -1.
−x
/-1=1/-1
x=-1
