Evaluate
4x−13x2
Rewrite the expression
x×4−x×13x
Factor out x from the expression
x(4−13x)
x(4−13x)=0
When the product of factors equals 0,at least one factor is 0
x=04−13x=0
Solve the equation for x
More Steps

Evaluate
4−13x=0
Move the constant to the right-hand side and change its sign
−13x=0−4
Removing 0 doesn't change the value,so remove it from the expression
−13x=−4
Change the signs on both sides of the equation
13x=4
Divide both sides
1313x=134
Divide the numbers
x=134
x=0x=134
Solution
x1=0,x2=134
