Question 55971This question is from textbook Algebra 2

: I'm in Chapter 6 section 6. Its about Alalyzing Graphs of Quadratic Functions. the problem looks like this: y=5x(squared) -6
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
