Find the roots
r1=−36114696,r2=36114696
Alternative Form
r1≈−2.323469,r2≈2.323469
Evaluate
r6×3−192−280
To find the roots of the expression,set the expression equal to 0
r6×3−192−280=0
Use the commutative property to reorder the terms
3r6−192−280=0
Subtract the numbers
3r6−472=0
Move the constant to the right-hand side and change its sign
3r6=0+472
Removing 0 doesn't change the value,so remove it from the expression
3r6=472
Divide both sides
33r6=3472
Divide the numbers
r6=3472
Take the root of both sides of the equation and remember to use both positive and negative roots
r=±63472
