How do you check is the equation is a extraneous solution pr not?
vampirchik [111]

We can check the equation is an extraneous solution or not by finding the solution and plugging it in the equation, to verify it.

<h3>What is the extraneous solution?</h3>

In mathematics, an extraneous solution is a solution that comes from the process of solving the problem but is not a genuine solution to the problem, such as the answer to an equation.

As we know from the definition the extraneous solution is a solution that comes from the process of solving the problem but is not a genuine solution to the problem.

Let's suppose the equation is:

\rm \sqrt{x+4} = x -2

Squaring both the sides:

x + 4 = (x - 2)²

x + 4 = x² - 4x + 4

x² -5x = 0

x = 0 or x = 5

Checking for the solution by plugging in the equation;

\rm \sqrt{5+4} = 5 -2

3 = 3

\rm \sqrt{0+4} = 0 -2

2 ≠ -2

The solution x = 0 shows extraneous solution.

Thus, we can check the equation is an extraneous solution or not by finding the solution and plugging it in the equation, to verify it.

An architect designs two houses that are shaped and positioned like a part of the branches of the hyperbola whose equation is wh
kogti [31]

Answer:

40 yards

Step-by-step explanation:

Data:

The hyperbola equation is expressed as follows:

625y^{2} -400x^{2}  = 250 000

Dividing each term by 250 000 gives:

\frac{625y^{2} }{250 000} - \frac{400x^{2} }{250 000} = \frac{250 000}{250 000}

\frac{y^{2} }{400} - \frac{x^{2} }{625} = 1

thus:

a² = 40

Therefore, the houses will be 20 yards apart.
