Answer:
Step-by-step explanation:
Your calculator can do this, but it's probably faster to do it in your head.
[tex]\left|\begin{array}{cc}a&b\\c&d\end{array}\right|=ad-cb[/tex]
__
[tex]\left|\begin{array}{cc}3&-1\\-3&4\end{array}\right|=(3)(4)-(-3)(-1)=9\\\\ \\\left|\begin{array}{cc}8&-1\\-4&-1\end{array}\right|=(8)(-1)-(-4)(-1)=-12[/tex]
And the next two rows are ...
(-12)(5) -(12)(-1) = -48 — (2)(-1) -(2)(-1) = 0
(0)(4) -(17)(-1) = 17 — (1)(1) -(0)(0) = 1
