In the first you must present the solution, step by step with comments and explanations, of the following exercises: 1) Factor 8x2 - 18x - 35. You can use the trial or ac method.

2) Find the function function or composite function f[g(x)] and g[f(x)] to solve the following problem: A store that wants to promote its sales announces a reduction in the price of certain items in a store. 30%. The function that describes this reduction is f(x) = x - 0.3x 0 let f(x)= 0.7x. It also announces another discount of $50 for each item that meets certain parameters. The function that reflects this discount is g(x) = x - 50. Compose the functions in both directions f[g(x)] and g[f(x)].

Use your function function to calculate the markdown price of an item that receives the combination of both markdowns and whose starting price is $1000. Is the same price? And if it is not, what is the reason for the difference?
