Question

Seja a matriz a= 2 x elevado a 2 2x-1 0
Se A = At encontre o valor de x

Answer 1

$\left[\begin{matrix} 2&x^2\\ 2x-1&0 \end{matrix}\right]=\left[\begin{matrix} 2&x^2\\ 2x-1&0 \end{matrix}\right]^t\\ \\ \left[\begin{matrix} 2&x^2\\ 2x-1&0 \end{matrix}\right]=\left[\begin{matrix} 2&2x-1\\ x^2&x-1&0 \end{matrix}\right]\\ \\ x^2=2x-1\\ x^2-2x+1=0\\ (x-1)^2=0\\ \\ \boxed{x=1}$
