Find the roots
x1=0,x2=27
Alternative Form
x1=0,x2=3.5
Evaluate
(2x−7)(2x×7)
To find the roots of the expression,set the expression equal to 0
(2x−7)(2x×7)=0
Multiply the terms
(2x−7)×14x=0
Multiply the terms
14x(2x−7)=0
Elimination the left coefficient
x(2x−7)=0
Separate the equation into 2 possible cases
x=02x−7=0
Solve the equation
More Steps

Evaluate
2x−7=0
Move the constant to the right-hand side and change its sign
2x=0+7
Removing 0 doesn't change the value,so remove it from the expression
2x=7
Divide both sides
22x=27
Divide the numbers
x=27
x=0x=27
Solution
x1=0,x2=27
Alternative Form
