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


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

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

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

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

Combine like terms: 35z + -1z = 34z
(-7 + 34z + 5z2) = 0

Solving
-7 + 34z + 5z2 = 0

Solving for variable 'z'.

Factor a trinomial.
