Question
Find the roots
h1=−42,h2=42
Alternative Form
h1≈−5.656854,h2≈5.656854
Evaluate
h2−32
To find the roots of the expression,set the expression equal to 0
h2−32=0
Move the constant to the right-hand side and change its sign
h2=0+32
Removing 0 doesn't change the value,so remove it from the expression
h2=32
Take the root of both sides of the equation and remember to use both positive and negative roots
h=±32
Simplify the expression
