25m2-110m+1215m-11=5m2-2×5m×11+1125m-11 =5m-1125m-11 Usedentity, a2-2ab+b2=a-b2 =5m-11Hence, 25m2-110m+1215m-11=5m-11

25m²-110m+121/5m-11

\frac{25 m^{2} - 110 m + 121}{5 m - 11} = \frac{{(5 m)}^{2} - 2 \times (5 m) \times (11) + {(11)}^{2}}{5 m - 11} = \frac{{(5 m - 11)}^{2}}{5 m - 11} [Usedentity, a^{2} - 2 ab + b^{2} = {(a - b)}^{2}] = 5 m - 11 Hence, \frac{25 m^{2} - 110 m + 121}{5 m - 11} = 5 m - 11
