I need help with the three following questions they're the level C questions in my pre-cal book and I just can't get them to look right 
1.) Multiply and write the result in standard form: (10 - 8i)(2 - 3i)
2.) How many possible rational roots are there for the function f(x) = 3x^3 +bx^2 - cx - 6 , where b and c are integers?
3.) P(x) is an even function and has x-intercepts at x = 2 and x = 3. What other values are also guaranteed to be x-intercepts?
