Solution for (7-z)(5z-3)=0 equation:


Simplifying
(7 + -1z)(5z + -3) = 0

Reorder the terms:
(7 + -1z)(-3 + 5z) = 0

Multiply (7 + -1z) * (-3 + 5z)
(7(-3 + 5z) + -1z * (-3 + 5z)) = 0
((-3 * 7 + 5z * 7) + -1z * (-3 + 5z)) = 0
((-21 + 35z) + -1z * (-3 + 5z)) = 0
(-21 + 35z + (-3 * -1z + 5z * -1z)) = 0
(-21 + 35z + (3z + -5z2)) = 0

Combine like terms: 35z + 3z = 38z
(-21 + 38z + -5z2) = 0
