\textbf{Given:}

\mathsf{f(a,b,c,d,w,x,y,z)=a^2+b^2-2c^2-3d^2+wx-yz}

\textbf{To find:}

\textsf{The value of}

\mathsf{f(5,-7,2,2,3,0,9,2)}

\textbf{Solution:}

\textsf{Consider,}

\mathsf{f(5,-7,2,2,3,0,9,2)}

\mathsf{=5^2+(-7)^2-2(2)^2-3(2)^2+(3{\times}0)-(9{\times}2)}

\mathsf{=25+49-2(4)-3(4)+(0)-(18)}

\mathsf{=25+49-8-12+(0)-18}

\mathsf{=74-38}

\mathsf{=36}

\implies\boxed{\mathsf{f(5,-7,2,2,3,0,9,2)=36}}
