Solution for (4z+3)(5-z)=0 equation:


Simplifying
(4z + 3)(5 + -1z) = 0

Reorder the terms:
(3 + 4z)(5 + -1z) = 0

Multiply (3 + 4z) * (5 + -1z)
(3(5 + -1z) + 4z * (5 + -1z)) = 0
((5 * 3 + -1z * 3) + 4z * (5 + -1z)) = 0
((15 + -3z) + 4z * (5 + -1z)) = 0
(15 + -3z + (5 * 4z + -1z * 4z)) = 0
(15 + -3z + (20z + -4z2)) = 0

Combine like terms: -3z + 20z = 17z
(15 + 17z + -4z2) = 0
