Solution for -(4z-4)(2z+6)=z(13-8z) equation:


Simplifying
-1(4z + -4)(2z + 6) = z(13 + -8z)

Reorder the terms:
-1(-4 + 4z)(2z + 6) = z(13 + -8z)

Reorder the terms:
-1(-4 + 4z)(6 + 2z) = z(13 + -8z)

Multiply (-4 + 4z) * (6 + 2z)
-1(-4(6 + 2z) + 4z * (6 + 2z)) = z(13 + -8z)
-1((6 * -4 + 2z * -4) + 4z * (6 + 2z)) = z(13 + -8z)
-1((-24 + -8z) + 4z * (6 + 2z)) = z(13 + -8z)
-1(-24 + -8z + (6 * 4z + 2z * 4z)) = z(13 + -8z)
-1(-24 + -8z + (24z + 8z2)) = z(13 + -8z)

Combine like terms: -8z + 24z = 16z
-1(-24 + 16z + 8z2) = z(13 + -8z)
(-24 * -1 + 16z * -1 + 8z2 * -1) = z(13 + -8z)
(24 + -16z + -8z2) = z(13 + -8z)
24 + -16z + -8z2 = (13 * z + -8z * z)
24 + -16z + -8z2 = (13z + -8z2)

Add '8z2' to each side of the equation.
24 + -16z + -8z2 + 8z2 = 13z + -8z2 + 8z2

Combine like terms: -8z2 + 8z2 = 0
24 + -16z + 0 = 13z + -8z2 + 8z2
24 + -16z = 13z + -8z2 + 8z2

Combine like terms: -8z2 + 8z2 = 0
24 + -16z = 13z + 0
24 + -16z = 13z

Solving
24 + -16z = 13z

Solving for variable 'z'.

Move all terms containing z to the left, all other terms to the right.

Add '-13z' to each side of the equation.
24 + -16z + -13z = 13z + -13z

Combine like terms: -16z + -13z = -29z
24 + -29z = 13z + -13z

Combine like terms: 13z + -13z = 0
24 + -29z = 0

Add '-24' to each side of the equation.
24 + -24 + -29z = 0 + -24

Combine like terms: 24 + -24 = 0
0 + -29z = 0 + -24
-29z = 0 + -24

Combine like terms: 0 + -24 = -24
-29z = -24

Divide each side by '-29'.
z = 0.8275862069

Simplifying
z = 0.8275862069
