X³ + 3x² = 25x + 75
x³ + 3x² - 25x - 75 = 0
x²(x + 3) - 25(x + 3) = 0
(x² - 25) * (x + 3) = 0
(x² - 25) = 0 (x + 3) = 0
x² = 25 x = -3
x = ±5
Hope this helps! :)

Answer:
-6n-32
Step-by-step explanation:
<span>First find how many grams are in 15.87kg and how many meters are in 30.48cm
15.87kg x 1000g/kg = 15, 870g
30.49cm x 1m/100cm = 0.3049m
Then, set up a proportion.
0.3049m/15, 870g = 1m/x g
Cross multiply to get..
0.3049x = 15, 870
Divide for x and there you are.</span>Source(s):Myself.1004 <span>· 8 years ago
