Quantum Mechanics $\Rightarrow$ }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).
