Solution for (2z-3)(z+4)=(3z-2)(z+6) equation:


Simplifying
(2z + -3)(z + 4) = (3z + -2)(z + 6)

Reorder the terms:
(-3 + 2z)(z + 4) = (3z + -2)(z + 6)

Reorder the terms:
(-3 + 2z)(4 + z) = (3z + -2)(z + 6)

Multiply (-3 + 2z) * (4 + z)
(-3(4 + z) + 2z * (4 + z)) = (3z + -2)(z + 6)
((4 * -3 + z * -3) + 2z * (4 + z)) = (3z + -2)(z + 6)
((-12 + -3z) + 2z * (4 + z)) = (3z + -2)(z + 6)
(-12 + -3z + (4 * 2z + z * 2z)) = (3z + -2)(z + 6)
(-12 + -3z + (8z + 2z2)) = (3z + -2)(z + 6)

Combine like terms: -3z + 8z = 5z
(-12 + 5z + 2z2) = (3z + -2)(z + 6)

Reorder the terms:
-12 + 5z + 2z2 = (-2 + 3z)(z + 6)

Reorder the terms:
-12 + 5z + 2z2 = (-2 + 3z)(6 + z)

Multiply (-2 + 3z) * (6 + z)
-12 + 5z + 2z2 = (-2(6 + z) + 3z * (6 + z))
-12 + 5z + 2z2 = ((6 * -2 + z * -2) + 3z * (6 + z))
-12 + 5z + 2z2 = ((-12 + -2z) + 3z * (6 + z))
-12 + 5z + 2z2 = (-12 + -2z + (6 * 3z + z * 3z))
-12 + 5z + 2z2 = (-12 + -2z + (18z + 3z2))

Combine like terms: -2z + 18z = 16z
-12 + 5z + 2z2 = (-12 + 16z + 3z2)

Add '12' to each side of the equation.
-12 + 5z + 12 + 2z2 = -12 + 16z + 12 + 3z2

-12 + 12 + 5z + 2z2 = -12 + 16z + 12 + 3z2

Combine like terms: -12 + 12 = 0
0 + 5z + 2z2 = -12 + 16z + 12 + 3z2
5z + 2z2 = -12 + 16z + 12 + 3z2

Reorder the terms:
5z + 2z2 = -12 + 12 + 16z + 3z2

Combine like terms: -12 + 12 = 0
5z + 2z2 = 0 + 16z + 3z2
5z + 2z2 = 16z + 3z2

Solving
5z + 2z2 = 16z + 3z2

Solving for variable 'z'.

Reorder the terms:
5z + -16z + 2z2 + -3z2 = 16z + 3z2 + -16z + -3z2

Combine like terms: 5z + -16z = -11z
-11z + 2z2 + -3z2 = 16z + 3z2 + -16z + -3z2

Combine like terms: 2z2 + -3z2 = -1z2
-11z + -1z2 = 16z + 3z2 + -16z + -3z2

Reorder the terms:
-11z + -1z2 = 16z + -16z + 3z2 + -3z2

Combine like terms: 16z + -16z = 0
-11z + -1z2 = 0 + 3z2 + -3z2
-11z + -1z2 = 3z2 + -3z2

Combine like terms: 3z2 + -3z2 = 0
-11z + -1z2 = 0

Factor out the Greatest Common Factor (GCF), '-1z'.
-1z(11 + z) = 0

Ignore the factor -1.

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 '(11 + z)' equal to zero and attempt to solve: Simplifying 11 + z = 0 Solving 11 + z = 0 Move all terms containing z to the left, all other terms to the right. Add '-11' to each side of the equation. 11 + -11 + z = 0 + -11 Combine like terms: 11 + -11 = 0 0 + z = 0 + -11 z = 0 + -11 Combine like terms: 0 + -11 = -11 z = -11 Simplifying z = -11

Solution

z = {0, -11}
