6v2−21085
Show Solution

Find the roots
v1=−6126510,v2=6126510
Alternative Form
v1≈−59.280407,v2≈59.280407
Evaluate
v2×6−21085
To find the roots of the expression,set the expression equal to 0
v2×6−21085=0
Use the commutative property to reorder the terms
6v2−21085=0
Move the constant to the right-hand side and change its sign
6v2=0+21085
Removing 0 doesn't change the value,so remove it from the expression
6v2=21085
Divide both sides
66v2=621085
Divide the numbers
v2=621085
Take the root of both sides of the equation and remember to use both positive and negative roots
