x^{2}-\frac{x_{211}}{3\times 10}+\frac{5948.4375\times 10000^{2}}{36\times 50000^{2}}=0
Cancel out 2\times 5000 in both numerator and denominator.
x^{2}-\frac{x_{211}}{30}+\frac{5948.4375\times 10000^{2}}{36\times 50000^{2}}=0
Multiply 3 and 10 to get 30.
x^{2}-\frac{x_{211}}{30}+\frac{5948.4375\times 100000000}{36\times 50000^{2}}=0
Calculate 10000 to the power of 2 and get 100000000.
x^{2}-\frac{x_{211}}{30}+\frac{594843750000}{36\times 50000^{2}}=0
Multiply 5948.4375 and 100000000 to get 594843750000.
x^{2}-\frac{x_{211}}{30}+\frac{594843750000}{36\times 2500000000}=0
Calculate 50000 to the power of 2 and get 2500000000.
x^{2}-\frac{x_{211}}{30}+\frac{594843750000}{90000000000}=0
Multiply 36 and 2500000000 to get 90000000000.
x^{2}-\frac{x_{211}}{30}+\frac{423}{64}=0
Reduce the fraction \frac{594843750000}{90000000000} to lowest terms by extracting and canceling out 1406250000.
x^{2}-\frac{32x_{211}}{960}+\frac{423\times 15}{960}=0
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 30 and 64 is 960. Multiply \frac{x_{211}}{30} times \frac{32}{32}. Multiply \frac{423}{64} times \frac{15}{15}.
x^{2}+\frac{-32x_{211}+423\times 15}{960}=0
Since -\frac{32x_{211}}{960} and \frac{423\times 15}{960} have the same denominator, add them by adding their numerators.
x^{2}+\frac{-32x_{211}+6345}{960}=0
Do the multiplications in -32x_{211}+423\times 15.
x^{2}-\frac{1}{30}x_{211}+\frac{423}{64}=0
Divide each term of -32x_{211}+6345 by 960 to get -\frac{1}{30}x_{211}+\frac{423}{64}.
-\frac{1}{30}x_{211}+\frac{423}{64}=-x^{2}
Subtract x^{2} from both sides. Anything subtracted from zero gives its negation.
-\frac{1}{30}x_{211}=-x^{2}-\frac{423}{64}
Subtract \frac{423}{64} from both sides.
\frac{-\frac{1}{30}x_{211}}{-\frac{1}{30}}=\frac{-x^{2}-\frac{423}{64}}{-\frac{1}{30}}
Multiply both sides by -30.
x_{211}=\frac{-x^{2}-\frac{423}{64}}{-\frac{1}{30}}
Dividing by -\frac{1}{30} undoes the multiplication by -\frac{1}{30}.
x_{211}=30x^{2}+\frac{6345}{32}
Divide -x^{2}-\frac{423}{64} by -\frac{1}{30} by multiplying -x^{2}-\frac{423}{64} by the reciprocal of -\frac{1}{30}.
