Use synthetic division and the Remainder Theorem to find P(a)
(like f(x) i think)
x^3+4x^2-8x-6
a= -2

Successful implementation of a new system is based on three independent modules. module 1 works properly with probability 0.96. for modules 2 and 3, these probabilities equal 0.95 and 0.90. compute the probability that at least one of these three modules fails to work properly.

Solve: 3x+y=6 4x-2y=18 show all work !
