Answer:

x=-2\\x=2

(You only need to give one solution)

Step-by-step explanation:

We have the following equation

(x^2+1)^2-5x^2-5=0

First, we need to foil out the parenthesis

x^4+2x^2+1-5x^2-5=0

Now we can combine the like terms

x^4-3x^2-4=0

Now, we need to factor this equation.

To factor this, we need to find a set of numbers that add together to get -3 and multiply to give us -4.

The pair of numbers that would do this would be 1 and -4.

This means that our factored form would be

(x^2-4)(x^2+1)=0

As the first binomial is a difference of squares, it can be factored futher into

(x^2+1)(x+2)(x-2)=0

Now, we can get our solutions.

The first binomial will produce two complex (Not real) solutions.

x+2=0\\\\x=-2

x-2=0\\\\x=2

So our solutions to this equation are

x=-2\\x=2

What is the distance between the longest dog in the shortest dog Short 7 over 8 longest 3 over 8 what is the difference
Step2247 [10]

Answer:

The distance between the longest dog and the shortest dog is 4 over 8 ( \frac{4}{8} ) OR 1 over 2 ( \frac{1}{2} )

Step-by-step explanation:

From the question,

Short is 7 over 8, that is,

Short = \frac{7}{8}

and longest is 3 over 8, that is

Longest = \frac{3}{8}

The distance between the longest dog and the shortest dog can be determined by finding the difference between the fractions. That is,

\frac{7}{8} - \frac{3}{8} = \frac{7 - 3}{8}

= \frac{4}{8}

= \frac{1}{2}

Hence, the distance between the longest dog and the shortest dog is 4 over 8 ( \frac{4}{8} ) OR 1 over 2 ( \frac{1}{2} ).
