(6+z)(3z+4)=0

Solution for (6+z)(3z+4)=0 equation:

Simplifying
(6 + z)(3z + 4) = 0

Reorder the terms:
(6 + z)(4 + 3z) = 0

Multiply (6 + z) * (4 + 3z)
(6(4 + 3z) + z(4 + 3z)) = 0
((4 * 6 + 3z * 6) + z(4 + 3z)) = 0
((24 + 18z) + z(4 + 3z)) = 0
(24 + 18z + (4 * z + 3z * z)) = 0
(24 + 18z + (4z + 3z2)) = 0

Combine like terms: 18z + 4z = 22z
(24 + 22z + 3z2) = 0

Solving
24 + 22z + 3z2 = 0

Solving for variable 'z'.

Factor a trinomial.
(6 + z)(4 + 3z) = 0
