[ 1/1 Equation]
Work: Find the solution of equation （-2.5xx+20x-30）*（2-x）^2+（0.5xx-5x+8）*（0.5xx-6x+10）*（2-x）-（-0.5xx+4x-6）*（（0.5xx-5x+8）+8（2-x）^2） = 0 .
Question type: Equation
Solution:
After the equation is converted into a general formula, there is a common factor:
( x - 2 )( x - 2 )
From
x - 2 = 0
x - 2 = 0
it is concluded that:：
x1=2
x2=2
Solutions that cannot be obtained by factorization:
x3≈2.318224 , keep 6 decimal places
x4≈6.727030 , keep 6 decimal places
x5≈17.954746 , keep 6 decimal places
There are 5 solution(s).
