$-1$

Vedclass · Answer

$\mathrm{R}_{1} ightarrow \mathrm{R}_{1}-2 \mathrm{R}_{2}+\mathrm{R}_{3}$

$\left|\begin{array}{ccc}{0} & {0} & {1} \ {\mathrm{x}+2} & {\mathrm{x}+3} & {\mathrm{x}+\mathrm{b}} \ {\mathrm{x}+3} & {\mathrm{x}+4} & {\mathrm{x}+\mathrm{c}}\end{array}ight|$

$\mathrm{R}_{3} ightarrow \mathrm{R}_{3}-\mathrm{R}_{2} \Rightarrow \Delta=-1$

જો $a\, -\, 2b + c = 1$ હોય તો $\left| {\begin{array}{*{20}{c}}
{x + 1}&{x + 2}&{x + a} \\
{x + 2}&{x + 3}&{x + b} \\
{x + 3}&{x + 4}&{x + c}
\end{array}} \right|$ મેળવો.
