Roots

The main dissimilarity between real and complex roots is that the real roots are obtained as real numbers, in contrast with the complex roots, which are indicated as imaginary numbers. The standard format for depicting any complex number is in the form of a + bi.

Printing A printer has a contract to run 20,000 postersfor a state fair. He can use any number of plates from1 to 8 to run the posters; each stamp of the press willproduce as many posters as there are plates. The costof printing all the posters is given byC(x) = 200 + 20x +180x , where x is the numberof plates.a. Combine the terms of this function over a common denominator to create a rational function.b. Use numerical or graphical methods to find thenumber of plates that will make the cost $336.c. How many plates should the printer create to produce the posters at the minimum cost?
