Mathematics

Answer:

Two

Step-by-step explanation:

When you solving square equation, you will have two solutions.

Here we are given ax^2 = c

We have to solve for x.

Divide both sides by a, we get

\frac{ax^2}{a} = \frac{a}{c}

Simplifying, we get

x^2 = \frac{a}{c}

In order to find the value of x, we need to get rid of square on the left side, so we need to take the square root on both sides, we get

\sqrt{x^2} = \sqrt{\frac{a}{c} }

x = ±\sqrt{\frac{a}{c} }

So you will have a positive number and a negative number.

Therefore, there are two solutions.

<h3>How to interpret Experiments?</h3>

There are different ways to carry out an experiment in mathematics. This is because there are various means of research and also ways to interpret the results.

Now, when comparing two treatment conditions, an independent-measures design would always obtain 1 score for each subject. However, when a repeated-measures design is carried out on the same sample, it will obtain 2 scores.
