Question
Simplify the expression
556s2−25
Evaluate
s2×556−25
Solution
556s2−25
Show Solution

Find the roots
s1=−2785139,s2=2785139
Alternative Form
s1≈−0.212047,s2≈0.212047
Evaluate
s2×556−25
To find the roots of the expression,set the expression equal to 0
s2×556−25=0
Use the commutative property to reorder the terms
556s2−25=0
Move the constant to the right-hand side and change its sign
556s2=0+25
Removing 0 doesn't change the value,so remove it from the expression
556s2=25
Divide both sides
556556s2=55625
Divide the numbers
s2=55625
Take the root of both sides of the equation and remember to use both positive and negative roots
s=±55625
