Start with the quadratic function: f(x) = ax2 + bx + c and follow the steps below. (a) Step 1: Show that (2 = (x+ 5)2 - Assume that a * 0. Hint: We did something like this when solving for the quadratic roots formula. (b) Step 2: That part of that depends on a is given by (x + 2 )2. We want to study exactly how (x + 7 )2 depends upon x. Show that: i. (x + + )2 2 0 for all values of x ii. (2 + 2a) 2 = 0 only when x = -2. so (xx + 2)- 6 )2 = 0 has 2 identical roots equal to b 2a
