Question
Find the roots
r1=−3,r2=3
Alternative Form
r1≈−1.732051,r2≈1.732051
Evaluate
r2−3
To find the roots of the expression,set the expression equal to 0
r2−3=0
Move the constant to the right-hand side and change its sign
r2=0+3
Removing 0 doesn't change the value,so remove it from the expression
r2=3
Take the root of both sides of the equation and remember to use both positive and negative roots
r=±3
Separate the equation into 2 possible cases
r=3r=−3
Solution
r1=−3,r2=3
Alternative Form
r1≈−1.732051,r2≈1.732051
