[ 1/1 Equation]
Work: Find the solution of equation x*x+(20/9)*x*x*(20/9) = 6.67*6.67 .
Question type: Equation
Solution:Original question:
| x | x | + | ( | 20 | ÷ | 9 | ) | x | x | ( | 20 | ÷ | 9 | ) | = | 667 100 | × | 667 100 |
| Left side of the equation = | x | x | + | 20 | ÷ | 9 | × | x | x | ( | 20 | ÷ | 9 | ) |
| = | x | x | + | 20 9 | x | x | ( | 20 | ÷ | 9 | ) |
| = | x | x | + | 20 9 | x | x | × | 20 | ÷ | 9 |
| = | x | x | + | 400 81 | x | x |
| x | x | + | 400 81 | x | x | = | 667 100 | × | 667 100 |
| Right side of the equation = | 444889 10000 |
| x | x | + | 400 81 | x | x | = | 444889 10000 |
The solution of the equation:
x1≈-2.737132 , keep 6 decimal places
x2≈2.737132 , keep 6 decimal places
There are 2 solution(s).
