$f(x_1,x_2)=x_1^2+x_1{x}_2+x_2^2+3x_1,$ Solve the unconstrained optimization problem for dis finsecioe by using Newton's numerical method starting from $x^{\text{'}}=\left[\begin{array}{c}0\mathrm{.}00\\ 0\mathrm{.}00\end{array}\right]$ with a termination criterion of $0\mathrm{.}91,$ bets, find the value of the function at this point points
