(-(two *x - three)^ two /(x^ two - three *x + two) + two)/(x^ two - three *x + two) = zero
( minus (2 multiply by x minus 3) squared divide by (x squared minus 3 multiply by x plus 2) plus 2) divide by (x squared minus 3 multiply by x plus 2) equally 0
( minus (two multiply by x minus three) to the power of two divide by (x to the power of two minus three multiply by x plus two) plus two) divide by (x to the power of two minus three multiply by x plus two) equally zero
