Select the correct answer from each drop-down menu. Three students used factoring to solve a quadratic equation.
X2 + 17x + 72 = 12
Jordan's Solution
Keith's Solution
r2 + 175 + 72 = 12
(x + 8) (x + 9) = 12
r2 + 17x + 72 = 12
r2 +177 + 60 = 0
(x + 5)(x + 12) = 0
Randall's Solution
1 2 + 171 + 72 = 12
22 +171 = -60
(t +17) = -60
I + 8 = 12
1 + 5 = 0
I = -60
and
r + 9 = 12
and
r + 12 = 0
and
1 +17 -60
