Answer:
v = − 1 or v = 3
Step-by-step explanation:
Let's solve your equation step-by-step.
[tex]v^{2}[/tex] − 2v = 3
Step 1: Subtract 3 from both sides.
[tex]v^{2}[/tex] − 2v − 3 = 3 − 3
[tex]v^{2}[/tex] − 2v − 3 = 0
Step 2: Factor left side of equation.
( v + 1 ) ( v − 3 ) = 0
Step 3: Set factors equal to 0.
v + 1 = 0 or v − 3 = 0
v = −1 or v = 3
