$LaTex: \vec a = \left( \begin{array}{l} 1 \\ 2 \\ \end{array} \right) \\ \vec b = \left( \begin{array}{l} x \\ x^2 \\ \end{array} \right) \\ 21 = 1 \times x + 2 \times x^2 \\ x = 3 \\$

$LaTex: \vec a = \left( \begin{array}{l} - 2 \\ x^2 - 4 \\ \end{array} \right) \\ \vec b = \left( \begin{array}{l} x - 2 \\ 4 \\ \end{array} \right) \\ 0 = - 2 \times \left( {x - 2} \right) + \left( {x^2 - 4} \right) \times 4 \\ x = 2 \\$
