Question

Choose the equation that best represents the general form of the following expression.

x^2/2=7x

- x 2 + 14x + 0
x 2 + 14x = 0
x 2 - 14x = 0
x 2 - 7x + 2 = 0

Answer 1

x^2 -14x = 0

Explanation:

The first step to do is to subtract 7x from both sides of the equation:

x^2/2 -7x = 7x -7x

x^2/2 -7x = 0

Now we can multiply both sides of the equation by 2, which get rid of the division symbol in the equation:

2(x^2/2 -7x = 0)

x^2 - 14x = 0

Hope this helped!

Answer 2

Here is how we get the equation that best represents the general form of the given expression above.
Since we have a fraction, what we are going to do in order to eliminate it is to multiply both sides by 2. So this gives us x^2 = 14x.
Move 14x, and the final form would be x^2 -14x = 0.
Hope this is the answer that you are looking for.
