☆2 equations
[ 1/2 Equation]
Work: Find the solution of equation 4p-6 = 0 .
Question type: Equation
Solution:Original question:
| 4 | p | − | 6 | = | 0 |
Transposition :
| 4 | p | = | 0 | + | 6 |
Combine the items on the right of the equation:
| 4 | p | = | 6 |
The coefficient of the unknown number is reduced to 1 :
| p | = | 6 | ÷ | 4 |
| = | 6 | × | 1 4 |
| = | 3 | × | 1 2 |
We obtained :
| p | = | 3 2 |
Convert the result to decimal form :
| p | = | 1.5 |
[ 2/2 Equation]
Work: Find the solution of equation 4p-6p^2+4p^3-p^4 = 80/81 .
Question type: Equation
Solution:
After the equation is converted into a general formula, it is converted into:
( 3p - 2 )( 3p - 4 )=0
From
3p - 2 = 0
3p - 4 = 0
it is concluded that:：
| p1= | 2 3 |
| p2= | 4 3 |
There are 2 solution(s).
