Question
Find the roots
r1=−415,r2=415
Alternative Form
r1≈−20.371549,r2≈20.371549
Evaluate
415−r2
To find the roots of the expression,set the expression equal to 0
415−r2=0
Move the constant to the right-hand side and change its sign
−r2=0−415
Removing 0 doesn't change the value,so remove it from the expression
−r2=−415
Change the signs on both sides of the equation
r2=415
Take the root of both sides of the equation and remember to use both positive and negative roots
r=±415
Separate the equation into 2 possible cases
r=415r=−415
Solution
r1=−415,r2=415
Alternative Form
r1≈−20.371549,r2≈20.371549
