Question

Solve the equation using the Quadratic Formula: * 2x2 – 2x - 2 = x2

Answer 1

Answer:

x = 2

Step-by-step explanation:

First we have to distinguish the whole numbers from the numbers with variables.

The 2's are all whole numbers, and both 2x's are the numbers with variables.

Then we need to seprate them on different sides on the equal sign.

To do this, we need to add 2x out from the left side, and subtract it into the right side.

Therefore, the equation will now be 2 x 2 - 2 = 2x + 2x.

Now we can simplify both sides.

Starting with the left side, 2 x 2 - 2 equals to 2.

On the right side, 2x + 2x equals to 4x.

Therefore, the equation will now be 2 = 4x.

We can switch this to 4x = 2 to make it easier.

Now we can divide both sides together.

The most easiest way to do this is by turning it into a fraction.

So $\frac{4}{2}$.

That equals to 2.

Therefore, x = 2.
