my question is when you write the quadratic funcionin vertex form, do you factor out a 5 and just have your x*x remaining and then subtract 6, or do you have x*x squared? This question is from textbook Algebra 2

Vertex form is highlight%28y=a%28x-h%29%5E2%2Bk%29, the vertex is (h,k)
Notice that x doesn't have a coefficient inside the parenthesis, if x^2 has a coefficient you factor, then complete the square. This one is different because a isn't 1 and there's no b.
y=5x%5E2-6
y=5%28x-0%29%5E2-6 is vertex form, the vertex is (0,-6), because a>1 the parabola is skinnier.
