(6-z)(6+z)=

Solution for (6-z)(6+z)= equation:

Simplifying
(6 + -1z)(6 + z) = 0

Multiply (6 + -1z) * (6 + z)
(6(6 + z) + -1z * (6 + z)) = 0
((6 * 6 + z * 6) + -1z * (6 + z)) = 0
((36 + 6z) + -1z * (6 + z)) = 0
(36 + 6z + (6 * -1z + z * -1z)) = 0
(36 + 6z + (-6z + -1z2)) = 0

Combine like terms: 6z + -6z = 0
(36 + 0 + -1z2) = 0
(36 + -1z2) = 0

Solving
36 + -1z2 = 0

Solving for variable 'z'.

Move all terms containing z to the left, all other terms to the right.

Add '-36' to each side of the equation.
36 + -36 + -1z2 = 0 + -36

Combine like terms: 36 + -36 = 0
0 + -1z2 = 0 + -36
-1z2 = 0 + -36

Combine like terms: 0 + -36 = -36
-1z2 = -36

Divide each side by '-1'.
z2 = 36

Simplifying
z2 = 36

Take the square root of each side:
z = {-6, 6}
