find all the zeros and write a linear factorization of g(x)=x^4-8x^3+27x^2-50x+50 given that 1+2i is a zero

solmaris [256]

Answer:

g(x)= (x-(1+2i)) * (x-(1-2i)) * (x-(3-i)) * (x-(3+i))

Please see attached image

Step-by-step explanation:

We can easily solve this equation by using a technical solver or a programming language such as Octave.

The linear factorization of the equation can be obtained directly by finding the zeros of g(x)

Please see attached images for the answer to your problem

g(x)= (x-(1+2i)) * (x-(1-2i)) * (x-(3-i)) * (x-(3+i))

If a fuel efficient car can go 210 miles

mars1129 [50]

Answer:

The distance covered by the car in 12 gallons of fuel is 630 miles.

Step-by-step explanation:

Distance covered by car in 4 gallons of fuel = 210 miles.

Let us use unitary method to find distance covered by car in 1 gallon of fuel.

Distance covered by car in 1 gallon of fuel = 210/4 miles.

Let us use unitary method to find distance covered by car in 12 gallon of fuel.

Distance covered by car in 12 gallons of fuel = (210/4)*12 = 630 miles.

What are the solutions of 2x2- 6x+5=0?

Scrat [10]

Answer:

$x_{1}=\frac{3}{2}+\frac{i}{2}\\$

$x_{2}=\frac{3}{2}-\frac{i}{2}$

Step-by-step explanation:

It is a Quadratic Equation

$2x^2-6x+5=0$

Once it cannot be easily factored, you solve it using the quadratic formula or completing the square. I will use the quadratic formula.

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

$x=\frac{-(-6)\pm\sqrt{(-6)^2-4\cdot 2\cdot 5}}{2\cdot 2}$

The discriminant is negative, therefore we got complex solutions.

$\Delta= \sqrt{-4}= \sqrt{4i} =2i$

$x=\frac{6\pm 2i}{4}$

$x_{1}=\frac{3+i}{2}$

$x_{2}=\frac{3-i}{2}$

Now, just rewrite the roots in standard complex form

$x_{1}=\frac{3}{2}+\frac{i}{2}\\$

$x_{2}=\frac{3}{2}-\frac{i}{2}$
