The exciting gameshow where contestants solve polynomials using factoring and the quadratic formula!

The steps Samsam took to correctly answer the final question!

1.) **y= x ^{2} + 4x + 4**

2.) **y= -10x ^{2} - 9x + 1**

3.) **y= -9x ^{2} - 9x + 6**

**** Be sure to try these yourself before looking at the answers in the next section****

1.) x = -2

2.) x = -1 and x = 1/10

3.) x = (3±sqrt(33))/ -6
