Question
Find the roots
t1=−15,t2=15
Alternative Form
t1≈−3.872983,t2≈3.872983
Evaluate
t2−15
To find the roots of the expression,set the expression equal to 0
t2−15=0
Move the constant to the right-hand side and change its sign
t2=0+15
Removing 0 doesn't change the value,so remove it from the expression
t2=15
Take the root of both sides of the equation and remember to use both positive and negative roots
t=±15
Separate the equation into 2 possible cases
t=15t=−15
Solution
t1=−15,t2=15
Alternative Form
t1≈−3.872983,t2≈3.872983
