Quantum Mechanics}Orthogonality

States or orthogonal when their dot-product (bra-ket) is 0. Since the eigenvectors |i\rangle are given as orthonormal, \langle i | i \rangle=1.

\langle \psi_i | \psi_2 \rangle =5-15+2x=0 Solve the equation to find that x=-10, as in choice (E).

Maybe if I post it as a "typo" someone will notice.
