Which equations have a leading coefficient of 3 and a constant term of –2? check all that apply.
0 = 3x2 + 2x – 2
0 = –2 – 3x2 + 3
0 = –3x + 3x2 – 2
0 = 3x2 + x + 2
0 = –1x – 2 + 3x2

Answers are: choice A, choice C, choice E

Explanation: The leading coefficient is the number that is to the left of the term with the largest exponent, which in this case is 2. The term 3x^2 is the leading term with the coefficient of 3. This is why the leading coefficient is 3 for choice A, choice C, and choice E. Choice B has a leading coefficient of -3 so we can rule that out. Choice D has a leading coefficient of 3, but the constant term is NOT -2. Instead the constant term is +2, so we can rule out choice D as well. The other choices that haven't been eliminated all have 3x^2 somewhere in them, as well as the constant term -2. The other x term isn't relevant to the restrictions placed in the instructions.
