How to find the roots of a polynomial of degree 4.

Mathematics
1 answer:
german3 years ago
7 0

Answer:

In this case, the factor that comes out is x=−3, so you would divide by (x+3). Repeat until you've reduced to a quadratic, and then use the quadratic formula to find the irrational coefficients (if any). Simple factorisation solves your problem. Hence the 4 roots are x=12,x=−3,x=2i and x=−2i.

17. Julie has $80 in her savings account and plans to save Sr each
marshall27 [118]

Answer:

$8(x + 10)

Step-by-step explanation:

The expression $8x + $80  has two terms. They are $8x and $80.

When you factor an expression, you are looking for numbers that every term in the expression can divide by (and give a whole number).

Just by looking at the terms, you see they both have $ you can factor out. They can both also be divided by 8. This is called taking out a common factor.

$8x + $80     Take out the common factor

= ($8x) / $8 + ($80) / $8

= $8(x + 10)      The common factor goes outside the terms' bracket

This expression can't be factored more because there are no common factors. The binomial also doesn't have square numbers for example, which might make a case where you need to factor further with different methods.

pashok25 [27]

Answer:

6.21\times 10^{-5}\ \text{light years}

Step-by-step explanation:

The distance light travels in one year is known as a light year.

1\ \text{light year}=5.87\times 10^{12}\ \text{miles}

The closest that Earth ever gets to Jupiter is 3.65\times 10^8\ \text{miles}

3.65\times 10^8\ \text{miles}=\dfrac{1}{5.87\times 10^{12}}\times 3.65\times 10^8\ \text{light years}\\\\=6.21\times 10^{-5}\ \text{light years}

Hence, the distance it will take light to travel from Earth to Jupiter at this distance is 6.21\times 10^{-5}\ \text{light years}
