Solution for (3z-8)(z+2)=3z^2+10 equation:


Simplifying
(3z + -8)(z + 2) = 3z2 + 10

Reorder the terms:
(-8 + 3z)(z + 2) = 3z2 + 10

Reorder the terms:
(-8 + 3z)(2 + z) = 3z2 + 10

Multiply (-8 + 3z) * (2 + z)
(-8(2 + z) + 3z * (2 + z)) = 3z2 + 10
((2 * -8 + z * -8) + 3z * (2 + z)) = 3z2 + 10
((-16 + -8z) + 3z * (2 + z)) = 3z2 + 10
(-16 + -8z + (2 * 3z + z * 3z)) = 3z2 + 10
(-16 + -8z + (6z + 3z2)) = 3z2 + 10

Combine like terms: -8z + 6z = -2z
(-16 + -2z + 3z2) = 3z2 + 10

Reorder the terms:
-16 + -2z + 3z2 = 10 + 3z2

Add '-3z2' to each side of the equation.
-16 + -2z + 3z2 + -3z2 = 10 + 3z2 + -3z2

Combine like terms: 3z2 + -3z2 = 0
-16 + -2z + 0 = 10 + 3z2 + -3z2
-16 + -2z = 10 + 3z2 + -3z2

Combine like terms: 3z2 + -3z2 = 0
-16 + -2z = 10 + 0
-16 + -2z = 10

Solving
-16 + -2z = 10

Solving for variable 'z'.

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

Add '16' to each side of the equation.
-16 + 16 + -2z = 10 + 16

Combine like terms: -16 + 16 = 0
0 + -2z = 10 + 16
-2z = 10 + 16

Combine like terms: 10 + 16 = 26
-2z = 26

Divide each side by '-2'.
z = -13

Simplifying
z = -13
