Show Solution

Find the roots
r1=−50005159506069,r2=50005159506069
Alternative Form
r1≈−0.015426,r2≈0.015426
Evaluate
238−1000102r2
To find the roots of the expression,set the expression equal to 0
238−1000102r2=0
Move the constant to the right-hand side and change its sign
−1000102r2=0−238
Removing 0 doesn't change the value,so remove it from the expression
−1000102r2=−238
Change the signs on both sides of the equation
1000102r2=238
Divide both sides
10001021000102r2=1000102238
Divide the numbers
r2=1000102238
Cancel out the common factor 2
r2=500051119
Take the root of both sides of the equation and remember to use both positive and negative roots
r=±500051119
