When Nick checked his work it did not match the
standard form function. Analyze Nick's work. What was
his mistake?
In step 1. he did not put the function in standard
form correctly
In step 2. he should have also factored -7 from the
constant term. 17.
In step 3. he did not subtract - 7(9) to keep the
function equivalent.
In step 4. he did not write the perfect square
trinomial correctly as a binomial squared.
