Question

Part 1: Solve each of the quadratic equations below. Show your work.

x2 – 36 = 0 and x2 = 8x – 12

Part 2: Describe what the solution(s) represent to the graph of each.

Part 3: How are the graphs alike? How are they different?

Answer 1

x2 -36=0
x2 = 36
x_1,_2= +/- sqrt36 = +/- 6

x2 -8x +12=0
(x-6)(x-2)=0
x-6=0
x=6 and
x-2=0
x=2
