okay so i'm trying to get ready for a math placement test, and well last time i took algebra was...my junior year in high school. so im a little rusty but can someone solve these for me
1. (3x-2y)^2= A. 9x^2-4y^2 B. 9x^2+4y^2 C. 9x^2-4y^2-6xy D. 9x^2-4y^2-12xy 2. x^2-x-6/x^2-4= A. x-3/2 B. x-3/x-2 c. x-3/x+2 D. 3/2 okay so I have the answers to them. This is suppose to be elementary algebra, and I feel dumb that I can't freaken figure out how they got the answers. Yea, those are the only ones I had trouble with. The one I'm having the most trouble with is 2. Idk, I really do feel dumb, so go ahead, say I'm dumb lol. anyway, I'll tell you guys if youre right or wrong. and I would like an explanatin on how to do these, specially number 2 I'm sure after I see the explanation, a light bulb with go off lol oh and srry for posting this on here, I figured I would get more responses and get em a lot faster. EDIT// okay so i figured out the first one... and almost figured out the second one so can someone help!! i wanna make sure i figured it out correctly |
