Question
Find the roots
p1=−2,p2=2
Alternative Form
p1≈−1.414214,p2≈1.414214
Evaluate
p2−2
To find the roots of the expression,set the expression equal to 0
p2−2=0
Move the constant to the right-hand side and change its sign
p2=0+2
Removing 0 doesn't change the value,so remove it from the expression
p2=2
Take the root of both sides of the equation and remember to use both positive and negative roots
p=±2
Separate the equation into 2 possible cases
p=2p=−2
Solution
p1=−2,p2=2
Alternative Form
p1≈−1.414214,p2≈1.414214
