Rewrite the expression
4x×3−4x×28x
Factor out 4x from the expression
4x(3−28x)
4x(3−28x)=0
When the product of factors equals 0,at least one factor is 0
4x=03−28x=0
Solve the equation for x
x=03−28x=0
Solve the equation for x
More Steps
Evaluate
3−28x=0
Move the constant to the right-hand side and change its sign
−28x=0−3
Removing 0 doesn't change the value,so remove it from the expression
−28x=−3
Change the signs on both sides of the equation
28x=3
Divide both sides
2828x=283
Divide the numbers
x=283
x=0x=283
