Can someone help me ?​

Answer 1

$\left[\begin{array}{ccc}1&0\\0&-1\\\end{array}\right]$×$\left[\begin{array}{ccc}0&3&0\\0&0&2\\\end{array}\right]$=$\left[\begin{array}{ccc}0&a&b\\0&c&d\\\end{array}\right]$

$\left[\begin{array}{ccc}0+0&3+0&0+0\\0+0&0+0&0(-2)\\\end{array}\right]$=$\left[\begin{array}{ccc}0&a&b\\0&c&d\\\end{array}\right]$

$\left[\begin{array}{ccc}0&3&0\\0&0&-2\\\end{array}\right]$=$\left[\begin{array}{ccc}0&a&b\\0&c&d\\\end{array}\right]$

$a=3$

$b=0$

$c=0$

$d=-2$
