sqrt(v+21)=v+1

Solution

v + 21 = v + 1

Solution

v = 4

Solution steps

v + 21 = v + 1

Square both sides:

v + 21 = v^{2} + 2 v + 1

v + 21 = v^{2} + 2 v + 1

Solve

v + 21 = v^{2} + 2 v + 1 : v = 4, v = - 5

v = 4, v = - 5

Verify Solutions:

v = 4

True

, v = - 5

False

The solution is

v = 4
