What is the factored form of y=x^3+3x^2-x-3 and what the zeros

PSYCHO15rus [73]

y = x³ + 3x² - x - 3
0 = x³ + 3x² - x - 3
0 = x²(x) + x²(3) - 1(x) - 1(3)
0 = x²(x + 3) - 1(x + 3)
0 = (x² - 1)(x + 3)
0 = (x² + x - x - 1)(x + 3)
0 = (x(x) + x(1) - 1(x) - 1(1))(x + 3)
0 = (x(x + 1) - 1(x + 1))(x + 3)
0 = (x - 1)(x + 1)(x + 3)
0 = x - 1 or 0 = x + 1 or 0 = x + 3
+ 1 + 1 - 1 - 1 - 3 - 3
1 = x or -1 = x or -3 = x

Solution Set: {-3, -1, 1}

The Newport Crab Company marks the location of its crab pots with colored balloons. They mark every fourth pot with a red balloo

sasho [114]

Answer: There are 310 pots that have three different colored balloons attached.

Step-by-step explanation:

Since we have given that

Number of crab pots in the bay = 600

Part of red balloon = $\dfrac{1}{4}$

Part of blue balloon = $\dfrac{1}{6}$

Part of yellow balloon = $\dfrac{1}{10}$

So, Number of pots that have different colored balloons attached is given by

$\dfrac{1}{4}\times 600+\dfrac{1}{6}\times 600+\dfrac{1}{10}\times 600\\\\=150+100+60\\\\=310$

Hence, there are 310 pots that have three different colored balloons attached.
