$f(x_1,x_2)=x_1^2+x_1{x}_2+x_2^2+3x_1,$ Solve the unconstrained optimization problem for fis function 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 terminatica criterion ar $0\mathrm{.}91$ ; deen, find the value of the function at this point $(20$ points$)$
