Question
Solve the equation
x1=0,x2=94
Alternative Form
x1=0,x2=0.4˙
Evaluate
5x2−9x3=x2
Move the expression to the left side
5x2−9x3−x2=0
Subtract the terms
More Steps

Evaluate
5x2−x2
Collect like terms by calculating the sum or difference of their coefficients
(5−1)x2
Subtract the numbers
4x2
4x2−9x3=0
Factor the expression
x2(4−9x)=0
Separate the equation into 2 possible cases
x2=04−9x=0
The only way a power can be 0 is when the base equals 0
x=04−9x=0
Solve the equation
More Steps

Evaluate
4−9x=0
Move the constant to the right-hand side and change its sign
−9x=0−4
Removing 0 doesn't change the value,so remove it from the expression
−9x=−4
Change the signs on both sides of the equation
9x=4
Divide both sides
99x=94
Divide the numbers
x=94
x=0x=94
Solution
x1=0,x2=94
Alternative Form
x1=0,x2=0.4˙
