Set 8: Quadratic Equations (Intermediate)

Choice A is correct. Choice A is the correct answer. To convert from vertex form to standard form: 1. Expand the squared binomial: $(x - 3)^2 = x^2 - 6 x + 9$. 2. Add the constant term: $(x^2 - 6 x + 9) + 2$. 3. Combine like terms: $x^2 - 6 x + 11$. Choice B is incorrect because it likely subtracted 2 instead of adding, or calculated $9 -4$. Choice C is incorrect because it misses the middle term $-6 x$. Choice D is incorrect because the middle term is $-2(3)x = -6 x$.
