Hi again! I'm being a serial pest, I know it- I'm sorry! If you can only help with one or two of these I would be grateful! thanks so much!
I need help with this inequality its a quadratic division- I' not sure how to approach it? Do I factor or use the Q formula?
x^2- 7x +10/ x^2 + 8x + 15 is < or = to 0
Have I solved this correctly?
log x + log(x -15)=2
log x =2- log(x -15)
x =2-x -15
Ive done this wrong haven't I?
And the Trig:
sin2x + sin5x=0
Not doing this one right either!
x^3 + x^2 + x +1 find all zeros real and complex - I just need to know how to tackle said problem, not the answer.
Thank you for any help at all!
