Solution for (Z-10)(z+10)= equation:


Simplifying
(Z + -10)(z + 10) = 0

Reorder the terms:
(-10 + Z)(z + 10) = 0

Reorder the terms:
(-10 + Z)(10 + z) = 0

Multiply (-10 + Z) * (10 + z)
(-10(10 + z) + Z(10 + z)) = 0
((10 * -10 + z * -10) + Z(10 + z)) = 0
((-100 + -10z) + Z(10 + z)) = 0
(-100 + -10z + (10 * Z + z * Z)) = 0
(-100 + -10z + (10Z + zZ)) = 0

Reorder the terms:
(-100 + 10Z + -10z + zZ) = 0
(-100 + 10Z + -10z + zZ) = 0

Solving
-100 + 10Z + -10z + zZ = 0

Solving for variable 'Z'.

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

Add '100' to each side of the equation.
-100 + 10Z + -10z + 100 + zZ = 0 + 100

Reorder the terms:
-100 + 100 + 10Z + -10z + zZ = 0 + 100

Combine like terms: -100 + 100 = 0
0 + 10Z + -10z + zZ = 0 + 100
10Z + -10z + zZ = 0 + 100

Combine like terms: 0 + 100 = 100
10Z + -10z + zZ = 100

Add '10z' to each side of the equation.
10Z + -10z + 10z + zZ = 100 + 10z

Combine like terms: -10z + 10z = 0
10Z + 0 + zZ = 100 + 10z
10Z + zZ = 100 + 10z

Reorder the terms:
-100 + 10Z + -10z + zZ = 100 + 10z + -100 + -10z

Reorder the terms:
-100 + 10Z + -10z + zZ = 100 + -100 + 10z + -10z

Combine like terms: 100 + -100 = 0
-100 + 10Z + -10z + zZ = 0 + 10z + -10z
-100 + 10Z + -10z + zZ = 10z + -10z

Combine like terms: 10z + -10z = 0
-100 + 10Z + -10z + zZ = 0
