(5z+2)(6-z)=0

Solution for (5z+2)(6-z)=0 equation:

Simplifying
(5z + 2)(6 + -1z) = 0

Reorder the terms:
(2 + 5z)(6 + -1z) = 0

Multiply (2 + 5z) * (6 + -1z)
(2(6 + -1z) + 5z * (6 + -1z)) = 0
((6 * 2 + -1z * 2) + 5z * (6 + -1z)) = 0
((12 + -2z) + 5z * (6 + -1z)) = 0
(12 + -2z + (6 * 5z + -1z * 5z)) = 0
(12 + -2z + (30z + -5z2)) = 0

Combine like terms: -2z + 30z = 28z
(12 + 28z + -5z2) = 0

Solving
12 + 28z + -5z2 = 0

Solving for variable 'z'.

0 + 5z = 0 + -2
5z = 0 + -2

Combine like terms: 0 + -2 = -2
5z = -2

Divide each side by '5'.
z = -0.4

Simplifying
z = -0.4
Solution
z = {6, -0.4}
