You can put this solution on YOUR website! I edited your question to what I thought you meant. If I'm wrong about you intent, please let me know.
Solve each equation. Round your answers to the nearest tenth when necessary.
x^3 - 5x^2 +4x = 0
x(x^2-5x+4)=0
x(x-4)(x-1)=0
x=0 or x-4=0 or x-1=0
x=0 or x-4+4=0+4 or x-1+1=0+1
x=0 or x=4 or x=1
:
Proof:
If x=0
(0)^3-5(0)^2+4(0)=0
0-5(0)+0=0
0=0
If x=4
(4)^3-5(4)^2+4(4)=0
64-5(16)+16=0
64-80+16=0
0=0
If x=1
(1)^3-5(1)^2+4(1)=0
1-5+4=0
0=0
We're right!!!
Happy Calculating!!!!
