(z-4)*(z-6)=

Solution for (z-4)*(z-6)= equation:

Simplifying
(z + -4)(z + -6) = 0

Reorder the terms:
(-4 + z)(z + -6) = 0

Reorder the terms:
(-4 + z)(-6 + z) = 0

Multiply (-4 + z) * (-6 + z)
(-4(-6 + z) + z(-6 + z)) = 0
((-6 * -4 + z * -4) + z(-6 + z)) = 0
((24 + -4z) + z(-6 + z)) = 0
(24 + -4z + (-6 * z + z * z)) = 0
(24 + -4z + (-6z + z2)) = 0

Combine like terms: -4z + -6z = -10z
(24 + -10z + z2) = 0

Solving
24 + -10z + z2 = 0

Solving for variable 'z'.

Factor a trinomial.
(4 + -1z)(6 + -1z) = 0

Subproblem 1
Set the factor '(4 + -1z)' equal to zero and attempt to solve:

Simplifying
4 + -1z = 0

Solving
4 + -1z = 0

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

Add '-4' to each side of the equation.
4 + -4 + -1z = 0 + -4

Combine like terms: 4 + -4 = 0
0 + -1z = 0 + -4
-1z = 0 + -4

Combine like terms: 0 + -4 = -4
-1z = -4

Divide each side by '-1'.
z = 4

Simplifying
z = 4
Subproblem 2
Set the factor '(6 + -1z)' equal to zero and attempt to solve:

Simplifying
6 + -1z = 0

Solving
6 + -1z = 0

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

Add '-6' to each side of the equation.
6 + -6 + -1z = 0 + -6

Combine like terms: 6 + -6 = 0
0 + -1z = 0 + -6
-1z = 0 + -6

Combine like terms: 0 + -6 = -6
-1z = -6

Divide each side by '-1'.
z = 6

Simplifying
z = 6
Solution
z = {4, 6}
