Ответ:
p(x) = x³+25x²+50x-1000 = (x-5)(x+10)(x+20)
Step-by-step explanation:
p(x) = x³+25x²+50x-1000
p(x) = (x-5)(x+10)(x-a)
x-a = ?
We can use Briot-Ruffini to find out.
As x-5 is a factor, we know that x-5=0 gives a root, so x=5 is a root of p(x)
As x+10 is a factor, we know that x+10=0 gives a root, so x=-10 is a root of p(x)
5 | 1 25 50 -1000
10 | 1 30 200 | 0
| 1 20 | 0
x + 20
So, p(x) = (x-5)(x+10)(x+20)
