[ 1/1 Equation]
Work: Find the solution of equation (280*14.44)/(14.44+4*z+4*z*z) = 60 .
Question type: Equation
Solution:Original question:
| ( | 280 | × | 361 25 | ) | ÷ | ( | 361 25 | + | 4 | z | + | 4 | z | z | ) | = | 60 |
| Multiply both sides of the equation by: | ( | 361 25 | + | 4 | z | + | 4 | z | z | ) |
| ( | 280 | × | 361 25 | ) | = | 60 | ( | 361 25 | + | 4 | z | + | 4 | z | z | ) |
| 280 | × | 361 25 | = | 60 | ( | 361 25 | + | 4 | z | + | 4 | z | z | ) |
| 280 | × | 361 25 | = | 60 | × | 361 25 | + | 60 | × | 4 | z | + | 60 | × | 4 | z | z |
20216 5 | = | 4332 5 | + | 240 | z | + | 240 | z | z |
The solution of the equation:
z1≈-4.172420 , keep 6 decimal places
z2≈3.172420 , keep 6 decimal places
There are 2 solution(s).
