Molly
Step-by-step explanation:
Brady did not properly create a square.
The square of a binomial is ...
(a -b)² = a² -2ab +b²
Where a²=x² and -2ab = -4x, you find b=2. The constant term in the square is 2²=4. Brady shows it as -4, which is incorrect.
Molly's work is correct.
Letter D would not be a quadratic.
x^2 + 3x - 2 = x^2 - 2x once simplified becomes
5x - 2 = 0 this is linear.
