Simplifying
(-11 + i)(-11 + -1i) = 0

Multiply (-11 + i) * (-11 + -1i)
(-11(-11 + -1i) + i(-11 + -1i)) = 0
((-11 * -11 + -1i * -11) + i(-11 + -1i)) = 0
((121 + 11i) + i(-11 + -1i)) = 0
(121 + 11i + (-11 * i + -1i * i)) = 0
(121 + 11i + (-11i + -1i2)) = 0

Combine like terms: 11i + -11i = 0
(121 + 0 + -1i2) = 0
(121 + -1i2) = 0
