Find the roots
s1=−811355,s2=811355
Alternative Form
s1≈−852.478739,s2≈852.478739
Evaluate
726720−s2×1
To find the roots of the expression,set the expression equal to 0
726720−s2×1=0
Any expression multiplied by 1 remains the same
726720−s2=0
Move the constant to the right-hand side and change its sign
−s2=0−726720
Removing 0 doesn't change the value,so remove it from the expression
−s2=−726720
Change the signs on both sides of the equation
s2=726720
Take the root of both sides of the equation and remember to use both positive and negative roots
s=±726720
