Question
Find the roots
a1=−5,a2=5
Alternative Form
a1≈−2.236068,a2≈2.236068
Evaluate
a2−5
To find the roots of the expression,set the expression equal to 0
a2−5=0
Move the constant to the right-hand side and change its sign
a2=0+5
Removing 0 doesn't change the value,so remove it from the expression
a2=5
Take the root of both sides of the equation and remember to use both positive and negative roots
a=±5
Separate the equation into 2 possible cases
a=5a=−5
Solution
a1=−5,a2=5
Alternative Form
a1≈−2.236068,a2≈2.236068
