1. \( f(x)=2 x^{2}+3 x-4 \) and \( g(x)=2 x+3 \), Find the \( (f+g)(x) \) and \( (g+f)(x) \)

1. Reduce las siguieutes expresiones algebraicas: a) \( m+2 m \) b) \( a+2 a+9 a \) c) \( m^{2}-2 m^{2}-7 m^{2} \) d) \( 6 x^{2} y^{2}-12 x^{2} y^{2}+x^{2} y^{2} \) c) \( 3 a-2 b-5 b+9 a \) f) \( a^{2}+b^{2}-2 b^{2}-3 a^{2}-a^{2}+b^{2} \) g) \( x^{2} y z+3 x y^{2} z-2 x y^{2} z-2 x^{2} y z \) h) \( 2 x-6 y-2 x-3 y-5 y \) i) \( 15 a+13 a-12 b-11 a-4 b-b \)

2. Efectuar \( \frac{x+2}{4 x}-\frac{3 x-1}{6 x^{2}} \) El m.c.d. \( =12 x^{2} \)

Simplify \( \left(2 x^{4} y^{4} z\right)^{2}\left(x^{5} y\right)^{4} \)

Determine whether the given procedure results in a binomial distribution. If not, state the reason why. Rolling a single die 26 times, keeping track of the numbers that are rolled A. Not binomial: the trials are not independent. B. Not binomial: there are too many trials. D. The procedure results in a binomial distribution.
