Solution for (5z-1)(7-z)=0 equation:


Simplifying
(5z + -1)(7 + -1z) = 0

Reorder the terms:
(-1 + 5z)(7 + -1z) = 0

Multiply (-1 + 5z) * (7 + -1z)
(-1(7 + -1z) + 5z * (7 + -1z)) = 0
((7 * -1 + -1z * -1) + 5z * (7 + -1z)) = 0
((-7 + 1z) + 5z * (7 + -1z)) = 0
(-7 + 1z + (7 * 5z + -1z * 5z)) = 0
(-7 + 1z + (35z + -5z2)) = 0

Combine like terms: 1z + 35z = 36z
(-7 + 36z + -5z2) = 0
