Question

Solutions of the equation: z2 - 12z + 36 = 0?

Answer 1

36 becomes a negative 

First -36 + -1 -37
Next: -18 + -2 = -20 
Next: -12 + -3 = -15
Next: -9 + -4 which equals -13
Finally we get to the last part: -6 + -6 = -12

We change z2 to $z^{2}$

$z^{2}$ - 6(z) = 36 

z(z) - 6

Because, we add up for the first two terms

Switch up, up the problem 6(z) - 6

Now, let's add the number 4 on the terms 
z - 6 (z - 6) 

Then, let's multiply z - 6 from z - 6 

$z - 6^{2} = ?$

From this problem we have to add 6 from the sides that we are working with 

Therefore, your answer for z is 6
