Solution for (4z-7)(3+z)= equation:


Simplifying
(4z + -7)(3 + z) = 0

Reorder the terms:
(-7 + 4z)(3 + z) = 0

Multiply (-7 + 4z) * (3 + z)
(-7(3 + z) + 4z * (3 + z)) = 0
((3 * -7 + z * -7) + 4z * (3 + z)) = 0
((-21 + -7z) + 4z * (3 + z)) = 0
(-21 + -7z + (3 * 4z + z * 4z)) = 0
(-21 + -7z + (12z + 4z2)) = 0

Combine like terms: -7z + 12z = 5z
(-21 + 5z + 4z2) = 0

Solving
-21 + 5z + 4z2 = 0

Solving for variable 'z'.
