seem to be needed along with synthetic division ... but I have no clue how to apply them. Here's an example of what I need to know how to do for my online precalculus class:
State how many imaginary and real zeros the function has.
f(x) = x^3 - 20x^2 + 123x - 216
t be larger than the space allotted which is 4 feet tall and 6 feet wide. The mosaic must be at least 3 feet tall and 5 feet wide. The tiles in the mosaic have words written on them and the artist wants the words to all be horizontal in the final mosaic. The word tiles come in two sizes: The smaller tiles are 4 inches tall and 4 inches wide, while the large tiles are 6 inches tall and 12 inches wide. If the small tiles cost $3.50 each and the larger tiles cost $4.50 each, how many of each should be used to minimize the cost? What is the minimum cost?
