Question 762543


|0 0 -1|
|3 x 0|= {{{x^2}}}
|2 0 3|

{{{ 0(3*x-0*0)-0(3*3-0*2)-1(3*0-x*2)=x^2}}}

{{{ 0(3x)-0(9)-1(0-2x)=x^2}}}

{{{2x=x^2}}}

{{{0=x^2-2x}}}

{{{0=x(x-2)}}}

{{{x=0}}} or {{{x=2}}}

check:

{{{0(0*3-0*0)-3(0*3-0*(-1))+2(0*0-0*(-1))=0}}}

{{{0(2*3-0*0)-3(0*3-0*(-1))+2(0*0-2*(-1))=4}}}
