Question

Solve the equation using the Quadratic Formula:

x2 + 6x + 3 = 0

Answer 1

x = -2
`(2)/(3)`

Explanation:

First we have to distinguish the numbers with x from the "normal" numbers.

2x and 6x are numbers with x.

3 and 0 are "normal" numbers.

Now we have to seperate them on different sides of the equal sign.

To do this, we can subtract 3 from the left side and then add it to 0 on the left side.

Therefore, the equation will now be 2x + 6x = -3.

Now we can add 2x and 6x together, making it 8x.

The equation will now be 8x = -3.

To find the product of x, we need to divide both sides together.

So 8 divided by -3 will make -2
`(2)/(3)`.

Therefore, x is -2
`(2)/(3)`.

Hope my explination makes sense :)
