Question

( 1 - v ) (5v +9 ) = 0Find v

Answer 1

Finding an unkown value

We know that if XY = 0 then there are two options: X = 0 or Y = 0

Then, in this case:

If ( 1 - v ) (5v +9 ) = 0​ then

( 1 - v ) = 0 or (5v +9) = 0

We find v for both cases:

1 - v₁ = 0

1 = v₁

5v₂ + 9 = 0

5v₂ = -9

v₂ = -9/5

Answer: v₁ = 1, v₂ = -9/5
