-2=-x+x square-4 firstly regroup the equation x square-2x+x-2=0 x square-x-2=0 multiply the first term by the last term.(I.e x square multiply by -2=-2x square) product of factor = -2x 1 sum of factor= -2x+1(x)= -1 x square -2x+x-2=0 open the bracket: x(x-2)+1(x-2)=0 x=1 or x=-2 Therefore; x=-1 or x=2
