Step-by-step explanation:

to find b in the equation :

b^2<4ac when having two complex roots

the required equation is x2 - Sx + P = 0

the sum of the roots :-1-i+-1-i=-2

the product=2

so the equation: x^2-(-2)x+2

Answer:

<h2>x² + 2x + 2 = 0</h2>

Step-by-step explanation:

Formula for finding a quadratic equation when its roots are given is

x² - ( sum of roots)x + product of roots=0

The roots are

- 1 + i

- 1 - i

Sum of roots is = - 1 + i - 1 - i = -2

Product of roots is = ( -1 + i)(- 1 - i)

= 1 + 1 = 2

So the quadratic equation is

x² - (-2)x + 2 = 0

<h3>x² + 2x + 2 = 0</h3>

Hope this helps you

Sedaia [141]

Answer:

Step-by-step explanation:

There are 47 acres and the farmer is planting 140,000 per acre.

You got to times 140,000 by 47 but you can multiply 14 by 47 instead and place the zero later.

So take 10 times 47 and that is 470

Then take 4 times 47 and that is 188

Add 470 and 188 and you get 658

Take 658 a place the four zeros and you get 6,580,000 seed

Last week, Bill ran 900 meters on each of 3 days. Between last week and this week, bill wants to run a total of 6 kilometers. Ho
laila [671]
For the 3 days he ran a total of :  3 * 900 = 2700 meters.

1000 meters = 1 kilometers

2700 meters = 2700 / 1000 = 2.7 kilometers.

Between last week and this week, Bill ran a total of 6 kilometers.

How far he ran this week = 6 - 2.7 = 3.3 kilometers.

Answer:

Step-by-step explanation:

For the first 30 hours, Andrew will earn 4(30) = $120.  For each additional hour beyond 30 that Andrew works, he will earn 5(h - 30).  Therefore, the function that gives Andrew's total wages when he works more than 30 hours is:

 

w = 120 + 5(h - 30).  

 

So, if he works 35 hours, he will earn:

 

120 + 5(35 - 30) = 120 + 5(5) = 120 + 25 = $145.

 

If he works 42 hours, he will earn:

 

120 + 5(42 - 30) = 120 + 5(12) = 120 + 60 = $180.

 

I hope this helps!
