Work: Find the solution of equation (19.453*x*x+44.218*x-0.9947)*5/1.857215863 = 47.73450035 .
Question type: Equation
Solution:Original question:
| ( | 19453 1000 | x | x | + | 22109 500 | x | − | 9947 10000 | ) | × | 5 | ÷ | 1857215863 1000000000 | = | 954690007 20000000 |
| Left side of the equation = | ( | 19453 1000 | x | x | + | 22109 500 | x | − | 9947 10000 | ) | × | 5000000000 1857215863 |
| ( | 19453 1000 | x | x | + | 22109 500 | x | − | 9947 10000 | ) | × | 5000000000 1857215863 | = | 954690007 20000000 |
| Left side of the equation = | 19453 1000 | x | x | × | 5000000000 1857215863 | + | 22109 500 | x | × | 5000000000 1857215863 | − | 9947 10000 | × | 5000000000 1857215863 |
