Question
Find the roots
h1=−2,h2=2
Alternative Form
h1≈−1.414214,h2≈1.414214
Evaluate
h2−2
To find the roots of the expression,set the expression equal to 0
h2−2=0
Move the constant to the right-hand side and change its sign
h2=0+2
Removing 0 doesn't change the value,so remove it from the expression
h2=2
Take the root of both sides of the equation and remember to use both positive and negative roots
h=±2
Separate the equation into 2 possible cases
h=2h=−2
Solution
h1=−2,h2=2
Alternative Form
h1≈−1.414214,h2≈1.414214
