Solution for (z-3)(2z+10)(z-1)= equation: 


Simplifying
(z + -3)(2z + 10)(z + -1) = 0

Reorder the terms:
(-3 + z)(2z + 10)(z + -1) = 0

Reorder the terms:
(-3 + z)(10 + 2z)(z + -1) = 0

Reorder the terms:
(-3 + z)(10 + 2z)(-1 + z) = 0

Multiply (-3 + z) * (10 + 2z)
(-3(10 + 2z) + z(10 + 2z))(-1 + z) = 0
((10 * -3 + 2z * -3) + z(10 + 2z))(-1 + z) = 0
((-30 + -6z) + z(10 + 2z))(-1 + z) = 0
(-30 + -6z + (10 * z + 2z * z))(-1 + z) = 0
(-30 + -6z + (10z + 2z2))(-1 + z) = 0

Combine like terms: -6z + 10z = 4z
(-30 + 4z + 2z2)(-1 + z) = 0

Multiply (-30 + 4z + 2z2) * (-1 + z)
(-30(-1 + z) + 4z * (-1 + z) + 2z2 * (-1 + z)) = 0
((-1 * -30 + z * -30) + 4z * (-1 + z) + 2z2 * (-1 + z)) = 0
((30 + -30z) + 4z * (-1 + z) + 2z2 * (-1 + z)) = 0
(30 + -30z + (-1 * 4z + z * 4z) + 2z2 * (-1 + z)) = 0
(30 + -30z + (-4z + 4z2) + 2z2 * (-1 + z)) = 0
(30 + -30z + -4z + 4z2 + (-1 * 2z2 + z * 2z2)) = 0
(30 + -30z + -4z + 4z2 + (-2z2 + 2z3)) = 0

Combine like terms: -30z + -4z = -34z
(30 + -34z + 4z2 + -2z2 + 2z3) = 0

Combine like terms: 4z2 + -2z2 = 2z2
(30 + -34z + 2z2 + 2z3) = 0

Solving
30 + -34z + 2z2 + 2z3 = 0

Solving for variable 'z'.
