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


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

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

Multiply (5 + -1z) * (-7 + 5z)
(5(-7 + 5z) + -1z * (-7 + 5z)) = 0
((-7 * 5 + 5z * 5) + -1z * (-7 + 5z)) = 0
((-35 + 25z) + -1z * (-7 + 5z)) = 0
(-35 + 25z + (-7 * -1z + 5z * -1z)) = 0
(-35 + 25z + (7z + -5z2)) = 0

Combine like terms: 25z + 7z = 32z
(-35 + 32z + -5z2) = 0
