Question
Find the roots
x1=−3,x2=3
Alternative Form
x1≈−1.732051,x2≈1.732051
Evaluate
x2−3
To find the roots of the expression,set the expression equal to 0
x2−3=0
Move the constant to the right-hand side and change its sign
x2=0+3
Removing 0 doesn't change the value,so remove it from the expression
x2=3
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±3
Separate the equation into 2 possible cases
x=3x=−3
Solution
x1=−3,x2=3
Alternative Form
x1≈−1.732051,x2≈1.732051
