Description

Problem 1. Write the following polynomials in the form a(x±h)2±k using the method we covered in class (by completing the square). Show all your work. (The ± just means that the signs don’t have to be a certain way, just do whatever’s natural.)
(a) x2+2x+3
(b) 2×2−4x+1
(c) 2×2+3x−2
(d) −3×2+2x+1

(g) 5×2+7x−2
(h) −5×2−3x+7

(k) ax2+bx+c
Problem 2. Check your answers from Problem 1 by converting them back into the form ax2±bx±c.
