Work: Find the solution of equation 1.12*1.12*X4+X2 = 1.12*1.12 .
Question type: Equation
Solution:Original question:
28 25 | × | 28 25 | X | × | 4 | + | X | × | 2 | = | 28 25 | × | 28 25 |
| Left side of the equation = | 3136 625 | X | + | X | × | 2 |
| = | 4386 625 | X |
4386 625 | X | = | 28 25 | × | 28 25 |
| Right side of the equation = | 784 625 |
4386 625 | X | = | 784 625 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 784 625 | ÷ | 4386 625 |
| = | 784 625 | × | 625 4386 |
| = | 392 | × | 1 2193 |
We obtained :
| X | = | 392 2193 |
Convert the result to decimal form :
| X | = | 0.178751 |
