In order to get on the track and field team, Anastacia must be able to find out what is the maximum height she needs to be able to jump. The team provides her with the expression −8x2+80x−191−8x2+80x−191 as one of the examples of height requirements she must complete during the try out. The team explains to her that she must write an equivalent expression to easily show the maximum height required. Her equivalent expression is -8( x - 5 )² + (-9, 9, 1/9) . Fill in the missing pieces of Anastacia’s expression.
The missing pieces of Anastacia's expression are:
-9, which is the constant term in the original expression
9, which is half of the coefficient of the x term in the original expression
1/9, which is the coefficient of the x^2 term in the original expression, divided by -8
