Hey! Got my algebra test back, several wrong..My professor does not go over anything, and I want to learn what I did wrong! Please, I appreciate any help! This is my only class left to graduate, and I can't let this pill of a professor take me down!
1) x^2-x+5 Let X= -3
2)x^4/x^5 Divide, write answers without negative exponents
3)6X^3y^5/3X^4y^2 Divide, write answers without negative exponents
4)(-2/x) ^ -3 Simplify, no negative exponents
5) (3b^-2/2a^-3)^2
6) (-5)^0
7) A Student scored 24 Points out of 40 on an examine. what percent of total points is this?
8)(2x^2+3x-2)-(3x^2-2x+4)
9)2x(3x^2y-6z)
10)(3x-2)(x+4)
11)(3x-2)(X^2+2x-4)
12)Change 3.24X10^-5 from scientific notation to a decimal.
OK, these are the 12 I got wrong, I appreciate it so much if you just explain one of them for me! I know this may seem like such easy stuff, but, I didn't go to HS due to a medical reason, and really want to pass Algebra already. If you need any help in Psychology, Biology,English, language tutoring, please feel free to ask me!!
