Question
Find the roots
h1=−7,h2=7
Alternative Form
h1≈−2.645751,h2≈2.645751
Evaluate
h2−7
To find the roots of the expression,set the expression equal to 0
h2−7=0
Move the constant to the right-hand side and change its sign
h2=0+7
Removing 0 doesn't change the value,so remove it from the expression
h2=7
Take the root of both sides of the equation and remember to use both positive and negative roots
h=±7
Separate the equation into 2 possible cases
h=7h=−7
Solution
h1=−7,h2=7
Alternative Form
h1≈−2.645751,h2≈2.645751
