Find the roots
s1=0,s2=310
Alternative Form
s1=0,s2=3.3˙
Evaluate
(3s×10)(3s−10)
To find the roots of the expression,set the expression equal to 0
(3s×10)(3s−10)=0
Multiply the terms
30s(3s−10)=0
Elimination the left coefficient
s(3s−10)=0
Separate the equation into 2 possible cases
s=03s−10=0
Solve the equation
More Steps

Evaluate
3s−10=0
Move the constant to the right-hand side and change its sign
3s=0+10
Removing 0 doesn't change the value,so remove it from the expression
3s=10
Divide both sides
33s=310
Divide the numbers
s=310
s=0s=310
Solution
s1=0,s2=310
Alternative Form
s1=0,s2=3.3˙
