Question
Solve the equation
x1=0,x2=72
Alternative Form
x1=0,x2=0.2˙85714˙
Evaluate
2x2−7x3=0
Factor the expression
x2(2−7x)=0
Separate the equation into 2 possible cases
x2=02−7x=0
The only way a power can be 0 is when the base equals 0
x=02−7x=0
Solve the equation
More Steps
Evaluate
2−7x=0
Move the constant to the right-hand side and change its sign
−7x=0−2
Removing 0 doesn't change the value,so remove it from the expression
−7x=−2
Change the signs on both sides of the equation
7x=2
Divide both sides
77x=72
Divide the numbers
x=72
x=0x=72
Solution
x1=0,x2=72
