Theorem lnopsubmuli

Description: Subtraction/product property of a linear Hilbert space operator. (Contributed by NM, 2-Jul-2005) (New usage is discouraged.)

	Hypothesis	lnopl.1	⊢ 𝑇 ∈ LinOp
	Assertion	lnopsubmuli	⊢ ( ( 𝐴 ∈ ℂ ∧ 𝐵 ∈ ℋ ∧ 𝐶 ∈ ℋ ) → ( 𝑇 ‘ ( 𝐵 −_ℎ ( 𝐴 ·_ℎ 𝐶 ) ) ) = ( ( 𝑇 ‘ 𝐵 ) −_ℎ ( 𝐴 ·_ℎ ( 𝑇 ‘ 𝐶 ) ) ) )
