Solution for (5z-1)(2z+3)=3z-3 equation:


Simplifying
(5z + -1)(2z + 3) = 3z + -3

Reorder the terms:
(-1 + 5z)(2z + 3) = 3z + -3

Reorder the terms:
(-1 + 5z)(3 + 2z) = 3z + -3

Multiply (-1 + 5z) * (3 + 2z)
(-1(3 + 2z) + 5z * (3 + 2z)) = 3z + -3
((3 * -1 + 2z * -1) + 5z * (3 + 2z)) = 3z + -3
((-3 + -2z) + 5z * (3 + 2z)) = 3z + -3
(-3 + -2z + (3 * 5z + 2z * 5z)) = 3z + -3
(-3 + -2z + (15z + 10z2)) = 3z + -3

Combine like terms: -2z + 15z = 13z
(-3 + 13z + 10z2) = 3z + -3

Reorder the terms:
-3 + 13z + 10z2 = -3 + 3z

Add '3' to each side of the equation.
-3 + 13z + 3 + 10z2 = -3 + 3 + 3z

Reorder the terms:
-3 + 3 + 13z + 10z2 = -3 + 3 + 3z

Combine like terms: -3 + 3 = 0
0 + 13z + 10z2 = -3 + 3 + 3z
13z + 10z2 = -3 + 3 + 3z

Combine like terms: -3 + 3 = 0
13z + 10z2 = 0 + 3z
13z + 10z2 = 3z

Solving
13z + 10z2 = 3z

Solving for variable 'z'.

Reorder the terms:
13z + -3z + 10z2 = 3z + -3z

Combine like terms: 13z + -3z = 10z
10z + 10z2 = 3z + -3z

Combine like terms: 3z + -3z = 0
10z + 10z2 = 0

Factor out the Greatest Common Factor (GCF), '10z'.
10z(1 + z) = 0

Ignore the factor 10.

Subproblem 1

Set the factor 'z' equal to zero and attempt to solve: Simplifying z = 0 Solving z = 0 Move all terms containing z to the left, all other terms to the right. Simplifying z = 0

Subproblem 2

Set the factor '(1 + z)' equal to zero and attempt to solve: Simplifying 1 + z = 0 Solving 1 + z = 0 Move all terms containing z to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + z = 0 + -1 Combine like terms: 1 + -1 = 0 0 + z = 0 + -1 z = 0 + -1 Combine like terms: 0 + -1 = -1 z = -1 Simplifying z = -1

Solution

z = {0, -1}
