(11z+10)(11z-10)=

Solution for (11z+10)(11z-10)= equation:

Simplifying
(11z + 10)(11z + -10) = 0

Reorder the terms:
(10 + 11z)(11z + -10) = 0

Reorder the terms:
(10 + 11z)(-10 + 11z) = 0

Multiply (10 + 11z) * (-10 + 11z)
(10(-10 + 11z) + 11z * (-10 + 11z)) = 0
((-10 * 10 + 11z * 10) + 11z * (-10 + 11z)) = 0
((-100 + 110z) + 11z * (-10 + 11z)) = 0
(-100 + 110z + (-10 * 11z + 11z * 11z)) = 0
(-100 + 110z + (-110z + 121z2)) = 0

Combine like terms: 110z + -110z = 0
(-100 + 0 + 121z2) = 0
(-100 + 121z2) = 0

Solving
-100 + 121z2 = 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 + 100 + 121z2 = 0 + 100

Combine like terms: -100 + 100 = 0
0 + 121z2 = 0 + 100
121z2 = 0 + 100

Combine like terms: 0 + 100 = 100
121z2 = 100

Divide each side by '121'.
z2 = 0.826446281

Simplifying
z2 = 0.826446281

Take the square root of each side:
z = {-0.909090909, 0.909090909}
