How to solve the Quadratic formul​

Mathematics
1 answer:
Marat540 [252]2 years ago
7 0

Answer:

The answer is x=-6, x=8

Step-by-step explanation:

I recommend using the quadratic formula to solve this problem.

x^2=a

-2x=b

-48=c

Plug it into the quadratic formula.

New equation:\frac{2+-\sqrt{(-2)^2-4(1)(-48)}}{2(1)}

Simplify

Equation: \frac{2+-\sqrt{4+192}}{2}

Add 4 and 192.

Equation: \frac{2+-\sqrt{196}}{2}

Do the square root of 196.

Equation: \frac{2+-14}{2}

Make into two different equations.

Equation 1: \frac{2+14}{2}

Equation 2: \frac{2-14}{2}

Solve the two equations and you will get -6 and 8.  Hope this helps!

Answer:

\sqrt{-5}=i\sqrt{5}

\sqrt{-25}=5i

Step-by-step explanation:

i is an imaginary unit, this means

i^2=-1

Rewrite -5 as 5\cdot (-1)=5\cdot i^2,

then

\sqrt{-5}=\sqrt{5i^2}=\sqrt{5}\cdot \sqrt{i^2}=\sqrt{5}\cdot i=i\sqrt{5}

Rewrite -25 as -25=25\cdot (-1)=25\cdot i^2,

then

\sqrt{-25}=\sqrt{25\cdot i^2}=\sqrt{25}\cdot \sqrt{i^2}=5\cdot i=5i

Solve <br>|-4b-8|+|-1-b^2|+2b^3. b= -2<br>show steps please .
evablogger [386]
Ok, first put in the -2 for each b. That gives:
|-4(-2)-8|+|-1(-(-2))^2|+2(-2)^3
Let's do each section.
The first section is |-4(-2)-8)|
-4 times -2 is 8, minus 8 is 0. The absolute value of 0 is still 0.
Now we move on to |-1(-(-2))^2)|
First we do exponents
-(-2) is 2, and 2^2 is 4. 4 times -1 is -4. The absolute value of -4 is 4
Now the last section, 2(-2)^3
Exponents first: (-2)^3 is -2 * -2 * -2, which is -8.
-8*2=-16.
0+4+(-16)=-12

Now suppose there are more goods and services and the economy is now open to trade with other countries. Based on this generated
OLEGan [10]

It should be noted that GDP deflator simply measures the changes in price for goods and services.

<h3>What is GDP?</h3>

Your information is incomplete as the figures aren't given. Therefore, an overview will be given.

Gross domestic product simply means the total monetary value of the finished goods and services that are produced in a country.

The formula for calculating the GDP deflator will be:

= Nominal GDP/Real GDP × 100

Also, the formula fro calculating real GDP per capita will be:

= Real GDP/Total population

In conclusion, the real GDP is the GDP of a country that has been adjusted for inflation.
