(two *x - five)/(x + one) - (x^ two - five *x + four)/(x + one)^ two = zero
(2 multiply by x minus 5) divide by (x plus 1) minus (x squared minus 5 multiply by x plus 4) divide by (x plus 1) squared equally 0
(two multiply by x minus five) divide by (x plus one) minus (x to the power of two minus five multiply by x plus four) divide by (x plus one) to the power of two equally zero
(2*x - 5)/(x + 1) - (x2 - 5*x + 4)/(x + 1)2 = 0
2*x - 5/x + 1 - x2 - 5*x + 4/x + 12 = 0
(2*x - 5)/(x + 1) - (x² - 5*x + 4)/(x + 1)² = 0
(2*x - 5)/(x + 1) - (x to the power of 2 - 5*x + 4)/(x + 1) to the power of 2 = 0
