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


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

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

Multiply (5 + z) * (-3 + 5z)
(5(-3 + 5z) + z(-3 + 5z)) = 0
((-3 * 5 + 5z * 5) + z(-3 + 5z)) = 0
((-15 + 25z) + z(-3 + 5z)) = 0
(-15 + 25z + (-3 * z + 5z * z)) = 0
(-15 + 25z + (-3z + 5z2)) = 0

Combine like terms: 25z + -3z = 22z
(-15 + 22z + 5z2) = 0

Solving
-15 + 22z + 5z2 = 0
