Question
Find the roots
a1=−30,a2=30
Alternative Form
a1≈−5.477226,a2≈5.477226
Evaluate
a2−30
To find the roots of the expression,set the expression equal to 0
a2−30=0
Move the constant to the right-hand side and change its sign
a2=0+30
Removing 0 doesn't change the value,so remove it from the expression
a2=30
Take the root of both sides of the equation and remember to use both positive and negative roots
a=±30
Separate the equation into 2 possible cases
a=30a=−30
Solution
a1=−30,a2=30
Alternative Form
a1≈−5.477226,a2≈5.477226
