Solve each quadratic equation by completing the square. give exact answers--no decimals.

Step-by-step explanation:

In this problem we have the equation of the following quadratic equation and we want to solve it using the method of square completion:

The steps are shown below:

For any equation of the form:

1. If the coefficient a is different from 1, then take a as a common factor.

In this case . Then:

2. Take the coefficient b that accompanies the variable x. In this case the coefficient is 4. Then, divide by 2 and the result squared it.

We have:

3. Add the term obtained in the previous step on both sides of equality, remember to multiply by the common factor :

4. Factor the resulting expression, and you will get:

Now solve the equation:

Note that the term is always therefore it can not be equal to -28.

The equation has no solution in real numbers.

In the same way we can find the complex roots:

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this
