x^2-3x-40= 0 please in the simplest way because I'm completely confused.
Jay from Glenwood, IL's Resources
8 + x - 8 = 10 x - 1 9 x - 1
y -5 = 3 - 1 - 2y y+4 y + 4
4 + 5 = 13 y 2y
2x+3y+4z=28 2x+y-z=0 x+y+3z=16
D y* C *=degrees _____________ / ...
I must use 2 variables and 2 equations. Im lost on the setup.
I need this to be explained as simple as possible because I am completely lost.
normally I would know hoe to solve this is a number was in the place of the x but since the x is there, I'm stuck.
I'm confused ??
I'm confused on the simplifying f(a)+f(2a).I could really use your help!!
I'm not sure how to solve this. I could really use your help!! I would really appreciate it if u explain if to me as simple as possible.Thanks !!
