Solve using the quadratic formula. \( -4 v^{2}-9 v+3=0 \) Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth. \( v=\square \) or \( v=\square \)

16. Completely factor the polynomial \( 5 x^{2}-20 x \) a \( 5 x(x-4 y) \) b \( 5\left(x^{2}-4 x y\right) \) c \( x(5 x-20 y) \) d \( x^{2}(5-4 y) \)

b) \( \left(\frac{3}{2}\right)^{-2}= \)

What is \( (f+g)(x) ? \) \[ \begin{aligned} f(x) & =3 x+5 \\ g(x) & =x^{2}+x-2\end{aligned} \]
