Let \(A=\left[\begin{array}{lll}\left(b+c\right)^2 & a^2 & a^2 \\ b^2 & \left(c+a\right)^2 & b^2\\ c^2 & c^2 & (a+b)^2\end{array}\right]\) where \(a,b\) and \(c\) are real numbers then determinant of \(A\) is |
\(2ab\left(a+b+c\right)^2\) \(2abc\left(a+b+c\right)^3\) \(abc\left(a+b+c\right)^2\) \(3abc\left(a+b+c\right)^2\) |
\(2abc\left(a+b+c\right)^3\) |
Use row and column operation |
