Alternative Form
x1=0,x2=2.3˙
Evaluate
(2x×11)(3x−7)
To find the roots of the expression,set the expression equal to 0
(2x×11)(3x−7)=0
Multiply the terms
22x(3x−7)=0
Elimination the left coefficient
x(3x−7)=0
Separate the equation into 2 possible cases
x=03x−7=0
Solve the equation
More Steps

Evaluate
3x−7=0
Move the constant to the right-hand side and change its sign
3x=0+7
Removing 0 doesn't change the value,so remove it from the expression
3x=7
Divide both sides
33x=37
Divide the numbers
x=37
x=0x=37
Solution
x1=0,x2=37
