Ok since we have \(\displaystyle v^2\) in our polynomial we need to think: What are two numbers that multiply to give us -75 and add up to -22? So after playing w/this a little bit you arrive at -25 and 3. Notice: 25 * -3 = -75 and -25 + (3) = -22. If we could not find these two number then we could just use the Quadratic Formula since I doubt you have learned difference of squares. Ok?
