Thanks for your help, stapel.. Here's what I got for the first one, x= i sqrt(5) and x=sqrt(3) i being the imaginary number of sqrt(-1) I'm not sure it is correct though :oops: For the second one, I can't seem to get the factors to add up to 7y (the middle term) so I'm stuck here I want to do (2z+1)...
I am having a really hard time with this section. My teacher will be absent tomorrow and I have a test on Monday. I don't understand this. So, for practice could anyone help me out and show me step by step how to do some problems? In my book, it says: "use the Vertex Form: y - k = a (x - h)^2 W...
Thanks stapel for the simple explanation. Here's the work I did for the 1st example. y = a(x - h)^2 + k 7 = a(4 - 3)^2 + 5 7 = a(1)^2 +5 7= a + 5 2 = a And the final answer is: y = 2(x-3)^2 + 5 For the second one I got 1/2 = a and the final answer/equation is: y = 1/2(x - (-1))^2 + 1 Are these corre...
