Please help, describe the error in the solving the equation

3. The second line should be or

3. So the roots are or

Step-by-step explanation:

Step 1:

If the function equals 0, we substitute all the separate factors to 0.

We keep the variable on the left side while all the other values go to the right side.

The given equation is

Step 2:

As given in step 1, we substitute all the separate factors to 0.

So or

So the roots are

So the roots are or

can you give me more detail on this! ?

step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
