Here's the proper explanation:
Since the vertex is (2,-1), the original equation will look like this: y=a*(x-2)^2-1
When the substitution happens we get to this:
0=a*(5-2)^2-1 then 1=a*(5-2)^2 -> 1=a*9
So, a=1/9! Written in another form:
1/9x^2-4/9x+4/9-1

filled cake. He divides the cake into 1/3 pieces. How much cake did each friend get?
6 I think because 6•3=18, 6•7=42, and 6•2=12
5n(n^2+n+7)-3n(n^2+2n)
<span>5n^3+5n^2+35n-3n^3-6n^2 </span>
<span>2n^3-n^2+35n </span>
<span>n(2n^2-n+35)</span>
